+Contact: Bjørn Mork <bjorn@mork.no>
+Description:
+ The driver will pad NCM Transfer Blocks (NTBs) longer
+ than this to tx_max, allowing the device to receive
+ tx_max sized frames with no terminating short
+ packet. NTBs shorter than this limit are transmitted
+ as-is, without any padding, and are terminated with a
+ short USB packet.
+
+ Padding to tx_max allows the driver to transmit NTBs
+ back-to-back without any interleaving short USB
+ packets. This reduces the number of short packet
+ interrupts in the device, and represents a tradeoff
+ between USB bus bandwidth and device DMA optimization.
+
+ Set to 0 to pad all frames. Set greater than tx_max to
+ disable all padding.

+Fixed link Device Tree binding
+------------------------------
+
+Some Ethernet MACs have a "fixed link", and are not connected to a
+normal MDIO-managed PHY device. For those situations, a Device Tree
+binding allows to describe a "fixed link".
+
+Such a fixed link situation is described by creating a 'fixed-link'
+sub-node of the Ethernet MAC device node, with the following
+properties:
+
+* 'speed' (integer, mandatory), to indicate the link speed. Accepted
+ values are 10, 100 and 1000
+* 'full-duplex' (boolean, optional), to indicate that full duplex is
+ used. When absent, half duplex is assumed.
+* 'pause' (boolean, optional), to indicate that pause should be
+ enabled.
+* 'asym-pause' (boolean, optional), to indicate that asym_pause should
+ be enabled.
+
+Old, deprecated 'fixed-link' binding:
+
+* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
+ form <a b c d e> with the following accepted values:
+ - a: emulated PHY ID, choose any but but unique to the all specified
+ fixed-links, from 0 to 31
+ - b: duplex configuration: 0 for half duplex, 1 for full duplex
+ - c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
+ - d: pause configuration: 0 for no pause, 1 for pause
+ - e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
+ asymmetric pause
+
+Example:
+
+ethernet@0 {
+ ...
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ ...
+};

+Network Control Model Devices" [2] optimized for Mobile Broadband
+devices, aka "3G/LTE modems".
+
+
+Command Line Parameters
+=======================
+
+The cdc_mbim driver has no parameters of its own. But the probing
+behaviour for NCM 1.0 backwards compatible MBIM functions (an
+"NCM/MBIM function" as defined in section 3.2 of [1]) is affected
+by a cdc_ncm driver parameter:
+
+prefer_mbim
+-----------
+Type: Boolean
+Valid Range: N/Y (0-1)
+Default Value: Y (MBIM is preferred)
+
+This parameter sets the system policy for NCM/MBIM functions. Such
+functions will be handled by either the cdc_ncm driver or the cdc_mbim
+driver depending on the prefer_mbim setting. Setting prefer_mbim=N
+makes the cdc_mbim driver ignore these functions and lets the cdc_ncm
+driver handle them instead.
+
+The parameter is writable, and can be changed at any time. A manual
+unbind/bind is required to make the change effective for NCM/MBIM
+functions bound to the "wrong" driver
+
+
+Basic usage
+===========
+
+MBIM functions are inactive when unmanaged. The cdc_mbim driver only
+provides an userspace interface to the MBIM control channel, and will
+not participate in the management of the function. This implies that a
+userspace MBIM management application always is required to enable a
+MBIM function.
+
+Such userspace applications includes, but are not limited to:
+ - mbimcli (included with the libmbim [3] library), and
+ - ModemManager [4]
+
+Establishing a MBIM IP session reequires at least these actions by the
+management application:
+ - open the control channel
+ - configure network connection settings
+ - connect to network
+ - configure IP interface
+
+Management application development
+----------------------------------
+The driver <-> userspace interfaces are described below. The MBIM
+control channel protocol is described in [1].
+
+
+MBIM control channel userspace ABI
+==================================
+
+/dev/cdc-wdmX character device
+------------------------------
+The driver creates a two-way pipe to the MBIM function control channel
+using the cdc-wdm driver as a subdriver. The userspace end of the
+control channel pipe is a /dev/cdc-wdmX character device.
+
+The cdc_mbim driver does not process or police messages on the control
+channel. The channel is fully delegated to the userspace management
+application. It is therefore up to this application to ensure that it
+complies with all the control channel requirements in [1].
+
+The cdc-wdmX device is created as a child of the MBIM control
+interface USB device. The character device associated with a specific
+MBIM function can be looked up using sysfs. For example:
+
+ bjorn@nemi:~$ ls /sys/bus/usb/drivers/cdc_mbim/2-4:2.12/usbmisc
+ cdc-wdm0
+
+ bjorn@nemi:~$ grep . /sys/bus/usb/drivers/cdc_mbim/2-4:2.12/usbmisc/cdc-wdm0/dev
+ 180:0
+
+
+USB configuration descriptors
+-----------------------------
+The wMaxControlMessage field of the CDC MBIM functional descriptor
+limits the maximum control message size. The managament application is
+responsible for negotiating a control message size complying with the
+requirements in section 9.3.1 of [1], taking this descriptor field
+into consideration.
+
+The userspace application can access the CDC MBIM functional
+descriptor of a MBIM function using either of the two USB
+configuration descriptor kernel interfaces described in [6] or [7].
+
+See also the ioctl documentation below.
+
+
+Fragmentation
+-------------
+The userspace application is responsible for all control message
+fragmentation and defragmentaion, as described in section 9.5 of [1].
+
+
+/dev/cdc-wdmX write()
+---------------------
+The MBIM control messages from the management application *must not*
+exceed the negotiated control message size.
+
+
+/dev/cdc-wdmX read()
+--------------------
+The management application *must* accept control messages of up the
+negotiated control message size.
+
+
+/dev/cdc-wdmX ioctl()
+--------------------
+IOCTL_WDM_MAX_COMMAND: Get Maximum Command Size
+This ioctl returns the wMaxControlMessage field of the CDC MBIM
+functional descriptor for MBIM devices. This is intended as a
+convenience, eliminating the need to parse the USB descriptors from
+userspace.
+
+ #include <stdio.h>
+ #include <fcntl.h>
+ #include <sys/ioctl.h>
+ #include <linux/types.h>
+ #include <linux/usb/cdc-wdm.h>
+ int main()
+ {
+ __u16 max;
+ int fd = open("/dev/cdc-wdm0", O_RDWR);
+ if (!ioctl(fd, IOCTL_WDM_MAX_COMMAND, &max))
+ printf("wMaxControlMessage is %d\n", max);
+ }
+
+
+Custom device services
+----------------------
+The MBIM specification allows vendors to freely define additional
+services. This is fully supported by the cdc_mbim driver.
+
+Support for new MBIM services, including vendor specified services, is
+implemented entirely in userspace, like the rest of the MBIM control
+protocol
+
+New services should be registered in the MBIM Registry [5].
+
+
+
+MBIM data channel userspace ABI
+===============================
+
+wwanY network device
+--------------------
+The cdc_mbim driver represents the MBIM data channel as a single
+network device of the "wwan" type. This network device is initially
+mapped to MBIM IP session 0.
+
+
+Multiplexed IP sessions (IPS)
+-----------------------------
+MBIM allows multiplexing up to 256 IP sessions over a single USB data
+channel. The cdc_mbim driver models such IP sessions as 802.1q VLAN
+subdevices of the master wwanY device, mapping MBIM IP session Z to
+VLAN ID Z for all values of Z greater than 0.
+
+The device maximum Z is given in the MBIM_DEVICE_CAPS_INFO structure
+described in section 10.5.1 of [1].
+
+The userspace management application is responsible for adding new
+VLAN links prior to establishing MBIM IP sessions where the SessionId
+is greater than 0. These links can be added by using the normal VLAN
+kernel interfaces, either ioctl or netlink.
+
+For example, adding a link for a MBIM IP session with SessionId 3:
+
+ ip link add link wwan0 name wwan0.3 type vlan id 3
+
+The driver will automatically map the "wwan0.3" network device to MBIM
+IP session 3.
+
+
+Device Service Streams (DSS)
+----------------------------
+MBIM also allows up to 256 non-IP data streams to be multiplexed over
+the same shared USB data channel. The cdc_mbim driver models these
+sessions as another set of 802.1q VLAN subdevices of the master wwanY
+device, mapping MBIM DSS session A to VLAN ID (256 + A) for all values
+of A.
+
+The device maximum A is given in the MBIM_DEVICE_SERVICES_INFO
+structure described in section 10.5.29 of [1].
+
+The DSS VLAN subdevices are used as a practical interface between the
+shared MBIM data channel and a MBIM DSS aware userspace application.
+It is not intended to be presented as-is to an end user. The
+assumption is that an userspace application initiating a DSS session
+also takes care of the necessary framing of the DSS data, presenting
+the stream to the end user in an appropriate way for the stream type.
+
+The network device ABI requires a dummy ethernet header for every DSS
+data frame being transported. The contents of this header is
+arbitrary, with the following exceptions:
+ - TX frames using an IP protocol (0x0800 or 0x86dd) will be dropped
+ - RX frames will have the protocol field set to ETH_P_802_3 (but will
+ not be properly formatted 802.3 frames)
+ - RX frames will have the destination address set to the hardware
+ address of the master device
+
+The DSS supporting userspace management application is responsible for
+adding the dummy ethernet header on TX and stripping it on RX.
+
+This is a simple example using tools commonly available, exporting
+DssSessionId 5 as a pty character device pointed to by a /dev/nmea
+symlink:
+
+ ip link add link wwan0 name wwan0.dss5 type vlan id 261
+ ip link set dev wwan0.dss5 up
+ socat INTERFACE:wwan0.dss5,type=2 PTY:,echo=0,link=/dev/nmea
+
+This is only an example, most suitable for testing out a DSS
+service. Userspace applications supporting specific MBIM DSS services
+are expected to use the tools and programming interfaces required by
+that service.
+
+Note that adding VLAN links for DSS sessions is entirely optional. A
+management application may instead choose to bind a packet socket
+directly to the master network device, using the received VLAN tags to
+map frames to the correct DSS session and adding 18 byte VLAN ethernet
+headers with the appropriate tag on TX. In this case using a socket
+filter is recommended, matching only the DSS VLAN subset. This avoid
+unnecessary copying of unrelated IP session data to userspace. For
+example:
+
+ static struct sock_filter dssfilter[] = {
+ /* use special negative offsets to get VLAN tag */
+ BPF_STMT(BPF_LD|BPF_B|BPF_ABS, SKF_AD_OFF + SKF_AD_VLAN_TAG_PRESENT),
+ BPF_JUMP(BPF_JMP|BPF_JEQ|BPF_K, 1, 0, 6), /* true */
+
+ /* verify DSS VLAN range */
+ BPF_STMT(BPF_LD|BPF_H|BPF_ABS, SKF_AD_OFF + SKF_AD_VLAN_TAG),
+ BPF_JUMP(BPF_JMP|BPF_JGE|BPF_K, 256, 0, 4), /* 256 is first DSS VLAN */
+ BPF_JUMP(BPF_JMP|BPF_JGE|BPF_K, 512, 3, 0), /* 511 is last DSS VLAN */
+
+ /* verify ethertype */
+ BPF_STMT(BPF_LD|BPF_H|BPF_ABS, 2 * ETH_ALEN),
+ BPF_JUMP(BPF_JMP|BPF_JEQ|BPF_K, ETH_P_802_3, 0, 1),
+
+ BPF_STMT(BPF_RET|BPF_K, (u_int)-1), /* accept */
+ BPF_STMT(BPF_RET|BPF_K, 0), /* ignore */
+ };
+
+
+
+Tagged IP session 0 VLAN
+------------------------
+As described above, MBIM IP session 0 is treated as special by the
+driver. It is initially mapped to untagged frames on the wwanY
+network device.
+
+This mapping implies a few restrictions on multiplexed IPS and DSS
+sessions, which may not always be practical:
+ - no IPS or DSS session can use a frame size greater than the MTU on
+ IP session 0
+ - no IPS or DSS session can be in the up state unless the network
+ device representing IP session 0 also is up
+
+These problems can be avoided by optionally making the driver map IP
+session 0 to a VLAN subdevice, similar to all other IP sessions. This
+behaviour is triggered by adding a VLAN link for the magic VLAN ID
+4094. The driver will then immediately start mapping MBIM IP session
+0 to this VLAN, and will drop untagged frames on the master wwanY
+device.
+
+Tip: It might be less confusing to the end user to name this VLAN
+subdevice after the MBIM SessionID instead of the VLAN ID. For
+example:
+
+ ip link add link wwan0 name wwan0.0 type vlan id 4094
+
+
+VLAN mapping
+------------
+
+Summarizing the cdc_mbim driver mapping described above, we have this
+relationship between VLAN tags on the wwanY network device and MBIM
+sessions on the shared USB data channel:
+
+ VLAN ID MBIM type MBIM SessionID Notes
+ ---------------------------------------------------------
+ untagged IPS 0 a)
+ 1 - 255 IPS 1 - 255 <VLANID>
+ 256 - 511 DSS 0 - 255 <VLANID - 256>
+ 512 - 4093 b)
+ 4094 IPS 0 c)
+
+ a) if no VLAN ID 4094 link exists, else dropped
+ b) unsupported VLAN range, unconditionally dropped
+ c) if a VLAN ID 4094 link exists, else dropped

+eBPF opcode encoding
+--------------------
+
+eBPF is reusing most of the opcode encoding from classic to simplify conversion
+of classic BPF to eBPF. For arithmetic and jump instructions the 8-bit 'code'
+field is divided into three parts:
+
+ +----------------+--------+--------------------+
+ | 4 bits | 1 bit | 3 bits |
+ | operation code | source | instruction class |
+ +----------------+--------+--------------------+
+ (MSB) (LSB)
+
+Three LSB bits store instruction class which is one of:
+
+ Classic BPF classes: eBPF classes:
+
+ BPF_LD 0x00 BPF_LD 0x00
+ BPF_LDX 0x01 BPF_LDX 0x01
+ BPF_ST 0x02 BPF_ST 0x02
+ BPF_STX 0x03 BPF_STX 0x03
+ BPF_ALU 0x04 BPF_ALU 0x04
+ BPF_JMP 0x05 BPF_JMP 0x05
+ BPF_RET 0x06 [ class 6 unused, for future if needed ]
+ BPF_MISC 0x07 BPF_ALU64 0x07
+
+When BPF_CLASS(code) == BPF_ALU or BPF_JMP, 4th bit encodes source operand ...
+
+ BPF_K 0x00
+ BPF_X 0x08
+
+ * in classic BPF, this means:
+
+ BPF_SRC(code) == BPF_X - use register X as source operand
+ BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
+
+ * in eBPF, this means:
+
+ BPF_SRC(code) == BPF_X - use 'src_reg' register as source operand
+ BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
+
+... and four MSB bits store operation code.
+
+If BPF_CLASS(code) == BPF_ALU or BPF_ALU64 [ in eBPF ], BPF_OP(code) is one of:
+
+ BPF_ADD 0x00
+ BPF_SUB 0x10
+ BPF_MUL 0x20
+ BPF_DIV 0x30
+ BPF_OR 0x40
+ BPF_AND 0x50
+ BPF_LSH 0x60
+ BPF_RSH 0x70
+ BPF_NEG 0x80
+ BPF_MOD 0x90
+ BPF_XOR 0xa0
+ BPF_MOV 0xb0 /* eBPF only: mov reg to reg */
+ BPF_ARSH 0xc0 /* eBPF only: sign extending shift right */
+ BPF_END 0xd0 /* eBPF only: endianness conversion */
+
+If BPF_CLASS(code) == BPF_JMP, BPF_OP(code) is one of:
+
+ BPF_JA 0x00
+ BPF_JEQ 0x10
+ BPF_JGT 0x20
+ BPF_JGE 0x30
+ BPF_JSET 0x40
+ BPF_JNE 0x50 /* eBPF only: jump != */
+ BPF_JSGT 0x60 /* eBPF only: signed '>' */
+ BPF_JSGE 0x70 /* eBPF only: signed '>=' */
+ BPF_CALL 0x80 /* eBPF only: function call */
+ BPF_EXIT 0x90 /* eBPF only: function return */
+
+So BPF_ADD | BPF_X | BPF_ALU means 32-bit addition in both classic BPF
+and eBPF. There are only two registers in classic BPF, so it means A += X.
+In eBPF it means dst_reg = (u32) dst_reg + (u32) src_reg; similarly,
+BPF_XOR | BPF_K | BPF_ALU means A ^= imm32 in classic BPF and analogous
+src_reg = (u32) src_reg ^ (u32) imm32 in eBPF.
+
+Classic BPF is using BPF_MISC class to represent A = X and X = A moves.
+eBPF is using BPF_MOV | BPF_X | BPF_ALU code instead. Since there are no
+BPF_MISC operations in eBPF, the class 7 is used as BPF_ALU64 to mean
+exactly the same operations as BPF_ALU, but with 64-bit wide operands
+instead. So BPF_ADD | BPF_X | BPF_ALU64 means 64-bit addition, i.e.:
+dst_reg = dst_reg + src_reg
+
+Classic BPF wastes the whole BPF_RET class to represent a single 'ret'
+operation. Classic BPF_RET | BPF_K means copy imm32 into return register
+and perform function exit. eBPF is modeled to match CPU, so BPF_JMP | BPF_EXIT
+in eBPF means function exit only. The eBPF program needs to store return
+value into register R0 before doing a BPF_EXIT. Class 6 in eBPF is currently
+unused and reserved for future use.
+
+For load and store instructions the 8-bit 'code' field is divided as:
+
+ +--------+--------+-------------------+
+ | 3 bits | 2 bits | 3 bits |
+ | mode | size | instruction class |
+ +--------+--------+-------------------+
+ (MSB) (LSB)
+
+Size modifier is one of ...
+
+ BPF_W 0x00 /* word */
+ BPF_H 0x08 /* half word */
+ BPF_B 0x10 /* byte */
+ BPF_DW 0x18 /* eBPF only, double word */
+
+... which encodes size of load/store operation:
+
+ B - 1 byte
+ H - 2 byte
+ W - 4 byte
+ DW - 8 byte (eBPF only)
+
+Mode modifier is one of:
+
+ BPF_IMM 0x00 /* classic BPF only, reserved in eBPF */
+ BPF_ABS 0x20
+ BPF_IND 0x40
+ BPF_MEM 0x60
+ BPF_LEN 0x80 /* classic BPF only, reserved in eBPF */
+ BPF_MSH 0xa0 /* classic BPF only, reserved in eBPF */
+ BPF_XADD 0xc0 /* eBPF only, exclusive add */
+
+eBPF has two non-generic instructions: (BPF_ABS | <size> | BPF_LD) and
+(BPF_IND | <size> | BPF_LD) which are used to access packet data.
+
+They had to be carried over from classic to have strong performance of
+socket filters running in eBPF interpreter. These instructions can only
+be used when interpreter context is a pointer to 'struct sk_buff' and
+have seven implicit operands. Register R6 is an implicit input that must
+contain pointer to sk_buff. Register R0 is an implicit output which contains
+the data fetched from the packet. Registers R1-R5 are scratch registers
+and must not be used to store the data across BPF_ABS | BPF_LD or
+BPF_IND | BPF_LD instructions.
+
+These instructions have implicit program exit condition as well. When
+eBPF program is trying to access the data beyond the packet boundary,
+the interpreter will abort the execution of the program. JIT compilers
+therefore must preserve this property. src_reg and imm32 fields are
+explicit inputs to these instructions.
+
+For example:
+
+ BPF_IND | BPF_W | BPF_LD means:
+
+ R0 = ntohl(*(u32 *) (((struct sk_buff *) R6)->data + src_reg + imm32))
+ and R1 - R5 were scratched.
+
+Unlike classic BPF instruction set, eBPF has generic load/store operations:
+
+BPF_MEM | <size> | BPF_STX: *(size *) (dst_reg + off) = src_reg
+BPF_MEM | <size> | BPF_ST: *(size *) (dst_reg + off) = imm32
+BPF_MEM | <size> | BPF_LDX: dst_reg = *(size *) (src_reg + off)
+BPF_XADD | BPF_W | BPF_STX: lock xadd *(u32 *)(dst_reg + off16) += src_reg
+BPF_XADD | BPF_DW | BPF_STX: lock xadd *(u64 *)(dst_reg + off16) += src_reg
+
+Where size is one of: BPF_B or BPF_H or BPF_W or BPF_DW. Note that 1 and
+2 byte atomic increments are not supported.
+
+Testing
+-------
+
+Next to the BPF toolchain, the kernel also ships a test module that contains
+various test cases for classic and internal BPF that can be executed against
+the BPF interpreter and JIT compiler. It can be found in lib/test_bpf.c and
+enabled via Kconfig:
+
+ CONFIG_TEST_BPF=m
+
+After the module has been built and installed, the test suite can be executed
+via insmod or modprobe against 'test_bpf' module. Results of the test cases
+including timings in nsec can be found in the kernel log (dmesg).

+ * Multiple transmit and receive queues:
+ * If supported, the backend will write the key "multi-queue-max-queues" to
+ * the directory for that vif, and set its value to the maximum supported
+ * number of queues.
+ * Frontends that are aware of this feature and wish to use it can write the
+ * key "multi-queue-num-queues", set to the number they wish to use, which
+ * must be greater than zero, and no more than the value reported by the backend
+ * in "multi-queue-max-queues".
+ *
+ * Queues replicate the shared rings and event channels.
+ * "feature-split-event-channels" may optionally be used when using
+ * multiple queues, but is not mandatory.
+ *
+ * Each queue consists of one shared ring pair, i.e. there must be the same
+ * number of tx and rx rings.
+ *
+ * For frontends requesting just one queue, the usual event-channel and
+ * ring-ref keys are written as before, simplifying the backend processing
+ * to avoid distinguishing between a frontend that doesn't understand the
+ * multi-queue feature, and one that does, but requested only one queue.
+ *
+ * Frontends requesting two or more queues must not write the toplevel
+ * event-channel (or event-channel-{tx,rx}) and {tx,rx}-ring-ref keys,
+ * instead writing those keys under sub-keys having the name "queue-N" where
+ * N is the integer ID of the queue for which those keys belong. Queues
+ * are indexed from zero. For example, a frontend with two queues and split
+ * event channels must write the following set of queue-related keys:
+ *
+ * /local/domain/1/device/vif/0/multi-queue-num-queues = "2"
+ * /local/domain/1/device/vif/0/queue-0 = ""
+ * /local/domain/1/device/vif/0/queue-0/tx-ring-ref = "<ring-ref-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/rx-ring-ref = "<ring-ref-rx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-tx = "<evtchn-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-rx = "<evtchn-rx0>"
+ * /local/domain/1/device/vif/0/queue-1 = ""
+ * /local/domain/1/device/vif/0/queue-1/tx-ring-ref = "<ring-ref-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/rx-ring-ref = "<ring-ref-rx1"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-tx = "<evtchn-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-rx = "<evtchn-rx1>"
+ *
+ * If there is any inconsistency in the XenStore data, the backend may
+ * choose not to connect any queues, instead treating the request as an
+ * error. This includes scenarios where more (or fewer) queues were
+ * requested than the frontend provided details for.
+ *
+ * Mapping of packets to queues is considered to be a function of the
+ * transmitting system (backend or frontend) and is not negotiated
+ * between the two. Guests are free to transmit packets on any queue

/*
* The TIPC locking policy is designed to ensure a very fine locking
* granularity, permitting complete parallel access to individual
- * port and node/link instances. The code consists of three major
+ * port and node/link instances. The code consists of four major
* locking domains, each protected with their own disjunct set of locks.
*
- * 1: The routing hierarchy.
- * Comprises the structures 'zone', 'cluster', 'node', 'link'
- * and 'bearer'. The whole hierarchy is protected by a big
- * read/write lock, tipc_net_lock, to enssure that nothing is added
- * or removed while code is accessing any of these structures.
- * This layer must not be called from the two others while they
- * hold any of their own locks.
- * Neither must it itself do any upcalls to the other two before
- * it has released tipc_net_lock and other protective locks.
+ * 1: The bearer level.
+ * RTNL lock is used to serialize the process of configuring bearer
+ * on update side, and RCU lock is applied on read side to make
+ * bearer instance valid on both paths of message transmission and
+ * reception.
*
- * Within the tipc_net_lock domain there are two sub-domains;'node' and
- * 'bearer', where local write operations are permitted,
- * provided that those are protected by individual spin_locks
- * per instance. Code holding tipc_net_lock(read) and a node spin_lock
- * is permitted to poke around in both the node itself and its
- * subordinate links. I.e, it can update link counters and queues,
- * change link state, send protocol messages, and alter the
- * "active_links" array in the node; but it can _not_ remove a link
- * or a node from the overall structure.
- * Correspondingly, individual bearers may change status within a
- * tipc_net_lock(read), protected by an individual spin_lock ber bearer
- * instance, but it needs tipc_net_lock(write) to remove/add any bearers.
+ * 2: The node and link level.
+ * All node instances are saved into two tipc_node_list and node_htable
+ * lists. The two lists are protected by node_list_lock on write side,
+ * and they are guarded with RCU lock on read side. Especially node
+ * instance is destroyed only when TIPC module is removed, and we can
+ * confirm that there has no any user who is accessing the node at the
+ * moment. Therefore, Except for iterating the two lists within RCU
+ * protection, it's no needed to hold RCU that we access node instance
+ * in other places.
*
+ * In addition, all members in node structure including link instances
+ * are protected by node spin lock.
*
- * 2: The transport level of the protocol.
- * This consists of the structures port, (and its user level
- * representations, such as user_port and tipc_sock), reference and
- * tipc_user (port.c, reg.c, socket.c).
+ * 3: The transport level of the protocol.
+ * This consists of the structures port, (and its user level
+ * representations, such as user_port and tipc_sock), reference and

+ ---help---
+ This option enables support for relaxation of the NO_IR flag for
+ situations that certain regulatory bodies have provided clarifications
+ on how relaxation can occur. This feature has an inherent dependency on
+ userspace features which must have been properly tested and as such is
+ not enabled by default.
+
+ A relaxation feature example is allowing the operation of a P2P group
+ owner (GO) on channels marked with NO_IR if there is an additional BSS
+ interface which associated to an AP which userspace assumes or confirms
+ to be an authorized master, i.e., with radar detection support and DFS
+ capabilities. However, note that in order to not create daisy chain
+ scenarios, this relaxation is not allowed in cases that the BSS client
+ is associated to P2P GO and in addition the P2P GO instantiated on
+ a channel due to this relaxation should not allow connection from
+ non P2P clients.
+
+ The regulatory core will apply these relaxations only for drivers that
+ support this feature by declaring the appropriate channel flags and
+ capabilities in their registration flow.
