+* Microchip ENC28J60
+
+This is a standalone 10 MBit ethernet controller with SPI interface.
+
+For each device connected to a SPI bus, define a child node within
+the SPI master node.
+
+Required properties:
+- compatible: Should be "microchip,enc28j60"
+- reg: Specify the SPI chip select the ENC28J60 is wired to
+- interrupt-parent: Specify the phandle of the source interrupt, see interrupt
+ binding documentation for details. Usually this is the GPIO bank
+ the interrupt line is wired to.
+- interrupts: Specify the interrupt index within the interrupt controller (referred
+ to above in interrupt-parent) and interrupt type. The ENC28J60 natively
+ generates falling edge interrupts, however, additional board logic
+ might invert the signal.
+- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
+- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
+ see also generic and your platform specific pinctrl binding
+ documentation.
+
+Optional properties:
+- spi-max-frequency: Maximum frequency of the SPI bus when accessing the ENC28J60.
+ According to the ENC28J80 datasheet, the chip allows a maximum of 20 MHz, however,
+ board designs may need to limit this value.
+- local-mac-address: See ethernet.txt in the same directory.

+Marvell 8897/8997 (sd8897/sd8997) SDIO devices
+------
+
+This node provides properties for controlling the marvell sdio wireless device.
+The node is expected to be specified as a child node to the SDIO controller that
+connects the device to the system.
+
+Required properties:
+
+ - compatible : should be one of the following:
+ * "marvell,sd8897"
+ * "marvell,sd8997"
+
+Optional properties:
+
+ - marvell,caldata* : A series of properties with marvell,caldata prefix,
+ represent calibration data downloaded to the device during
+ initialization. This is an array of unsigned 8-bit values.
+ the properties should follow below property name and
+ corresponding array length:
+ "marvell,caldata-txpwrlimit-2g" (length = 566).
+ "marvell,caldata-txpwrlimit-5g-sub0" (length = 502).
+ "marvell,caldata-txpwrlimit-5g-sub1" (length = 688).
+ "marvell,caldata-txpwrlimit-5g-sub2" (length = 750).
+ "marvell,caldata-txpwrlimit-5g-sub3" (length = 502).
+ - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured
+ to firmware. Firmware will wakeup the host using this pin
+ during suspend/resume.
+ - interrupt-parent: phandle of the parent interrupt controller
+ - interrupts : interrupt pin number to the cpu. driver will request an irq based on
+ this interrupt number. during system suspend, the irq will be enabled
+ so that the wifi chip can wakeup host platform under certain condition.
+ during system resume, the irq will be disabled to make sure
+ unnecessary interrupt is not received.
+
+Example:
+
+Tx power limit calibration data is configured in below example.
+The calibration data is an array of unsigned values, the length
+can vary between hw versions.
+IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured
+so that firmware can wakeup host using this device side pin.

+Segmentation Offloads in the Linux Networking Stack
+
+Introduction
+============
+
+This document describes a set of techniques in the Linux networking stack
+to take advantage of segmentation offload capabilities of various NICs.
+
+The following technologies are described:
+ * TCP Segmentation Offload - TSO
+ * UDP Fragmentation Offload - UFO
+ * IPIP, SIT, GRE, and UDP Tunnel Offloads
+ * Generic Segmentation Offload - GSO
+ * Generic Receive Offload - GRO
+ * Partial Generic Segmentation Offload - GSO_PARTIAL
+
+TCP Segmentation Offload
+========================
+
+TCP segmentation allows a device to segment a single frame into multiple
+frames with a data payload size specified in skb_shinfo()->gso_size.
+When TCP segmentation requested the bit for either SKB_GSO_TCP or
+SKB_GSO_TCP6 should be set in skb_shinfo()->gso_type and
+skb_shinfo()->gso_size should be set to a non-zero value.
+
+TCP segmentation is dependent on support for the use of partial checksum
+offload. For this reason TSO is normally disabled if the Tx checksum
+offload for a given device is disabled.
+
+In order to support TCP segmentation offload it is necessary to populate
+the network and transport header offsets of the skbuff so that the device
+drivers will be able determine the offsets of the IP or IPv6 header and the
+TCP header. In addition as CHECKSUM_PARTIAL is required csum_start should
+also point to the TCP header of the packet.
+
+For IPv4 segmentation we support one of two types in terms of the IP ID.
+The default behavior is to increment the IP ID with every segment. If the
+GSO type SKB_GSO_TCP_FIXEDID is specified then we will not increment the IP
+ID and all segments will use the same IP ID. If a device has
+NETIF_F_TSO_MANGLEID set then the IP ID can be ignored when performing TSO
+and we will either increment the IP ID for all frames, or leave it at a
+static value based on driver preference.
+
+UDP Fragmentation Offload
+=========================
+
+UDP fragmentation offload allows a device to fragment an oversized UDP
+datagram into multiple IPv4 fragments. Many of the requirements for UDP
+fragmentation offload are the same as TSO. However the IPv4 ID for
+fragments should not increment as a single IPv4 datagram is fragmented.
+
+IPIP, SIT, GRE, UDP Tunnel, and Remote Checksum Offloads
+========================================================
+
+In addition to the offloads described above it is possible for a frame to
+contain additional headers such as an outer tunnel. In order to account
+for such instances an additional set of segmentation offload types were
+introduced including SKB_GSO_IPIP, SKB_GSO_SIT, SKB_GSO_GRE, and
+SKB_GSO_UDP_TUNNEL. These extra segmentation types are used to identify
+cases where there are more than just 1 set of headers. For example in the
+case of IPIP and SIT we should have the network and transport headers moved
+from the standard list of headers to "inner" header offsets.
+
+Currently only two levels of headers are supported. The convention is to
+refer to the tunnel headers as the outer headers, while the encapsulated
+data is normally referred to as the inner headers. Below is the list of
+calls to access the given headers:
+
+IPIP/SIT Tunnel:
+ Outer Inner
+MAC skb_mac_header
+Network skb_network_header skb_inner_network_header
+Transport skb_transport_header
+
+UDP/GRE Tunnel:
+ Outer Inner
+MAC skb_mac_header skb_inner_mac_header
+Network skb_network_header skb_inner_network_header
+Transport skb_transport_header skb_inner_transport_header
+
+In addition to the above tunnel types there are also SKB_GSO_GRE_CSUM and
+SKB_GSO_UDP_TUNNEL_CSUM. These two additional tunnel types reflect the
+fact that the outer header also requests to have a non-zero checksum
+included in the outer header.
+
+Finally there is SKB_GSO_REMCSUM which indicates that a given tunnel header
+has requested a remote checksum offload. In this case the inner headers
+will be left with a partial checksum and only the outer header checksum
+will be computed.
+
+Generic Segmentation Offload
+============================
+
+Generic segmentation offload is a pure software offload that is meant to
+deal with cases where device drivers cannot perform the offloads described
+above. What occurs in GSO is that a given skbuff will have its data broken
+out over multiple skbuffs that have been resized to match the MSS provided
+via skb_shinfo()->gso_size.
+
+Before enabling any hardware segmentation offload a corresponding software
+offload is required in GSO. Otherwise it becomes possible for a frame to
+be re-routed between devices and end up being unable to be transmitted.
+
+Generic Receive Offload
+=======================
+
+Generic receive offload is the complement to GSO. Ideally any frame
+assembled by GRO should be segmented to create an identical sequence of
+frames using GSO, and any sequence of frames segmented by GSO should be
+able to be reassembled back to the original by GRO. The only exception to
+this is IPv4 ID in the case that the DF bit is set for a given IP header.
+If the value of the IPv4 ID is not sequentially incrementing it will be
+altered so that it is when a frame assembled via GRO is segmented via GSO.
+
+Partial Generic Segmentation Offload
+====================================
+
+Partial generic segmentation offload is a hybrid between TSO and GSO. What
+it effectively does is take advantage of certain traits of TCP and tunnels
+so that instead of having to rewrite the packet headers for each segment
+only the inner-most transport header and possibly the outer-most network
+header need to be updated. This allows devices that do not support tunnel
+offloads or tunnel offloads with checksum to still make use of segmentation.
+
+With the partial offload what occurs is that all headers excluding the
+inner transport header are updated such that they will contain the correct
+values for if the header was simply duplicated. The one exception to this
+is the outer IPv4 ID field. It is up to the device drivers to guarantee
+that the IPv4 ID field is incremented in the case that a given header does
+not have the DF bit set.

+4.12) TSO support (GMAC4.x)
+
+TSO (Tcp Segmentation Offload) feature is supported by GMAC 4.x chip family.
+When a packet is sent through TCP protocol, the TCP stack ensures that
+the SKB provided to the low level driver (stmmac in our case) matches with
+the maximum frame len (IP header + TCP header + payload <= 1500 bytes (for
+MTU set to 1500)). It means that if an application using TCP want to send a
+packet which will have a length (after adding headers) > 1514 the packet
+will be split in several TCP packets: The data payload is split and headers
+(TCP/IP ..) are added. It is done by software.
+
+When TSO is enabled, the TCP stack doesn't care about the maximum frame
+length and provide SKB packet to stmmac as it is. The GMAC IP will have to
+perform the segmentation by it self to match with maximum frame length.
+
+This feature can be enabled in device tree through "snps,tso" entry.

/**
+ * DOC: DQA - Dynamic Queue Allocation -introduction
+ *
+ * Dynamic Queue Allocation (AKA "DQA") is a feature implemented in iwlwifi
+ * driver to allow dynamic allocation of queues on-demand, rather than allocate
+ * them statically ahead of time. Ideally, we would like to allocate one queue
+ * per RA/TID, thus allowing an AP - for example - to send BE traffic to STA2
+ * even if it also needs to send traffic to a sleeping STA1, without being
+ * blocked by the sleeping station.
+ *
+ * Although the queues in DQA mode are dynamically allocated, there are still
+ * some queues that are statically allocated:
+ * TXQ #0 - command queue
+ * TXQ #1 - aux frames
+ * TXQ #2 - P2P device frames
+ * TXQ #3 - P2P GO/SoftAP GCAST/BCAST frames
+ * TXQ #4 - BSS DATA frames queue
+ * TXQ #5-8 - Non-QoS and MGMT frames queue pool
+ * TXQ #9 - P2P GO/SoftAP probe responses
+ * TXQ #10-31 - DATA frames queue pool
+ * The queues are dynamically taken from either the MGMT frames queue pool or
+ * the DATA frames one. See the %iwl_mvm_dqa_txq for more information on every
+ * queue.
+ *
+ * When a frame for a previously unseen RA/TID comes in, it needs to be deferred
+ * until a queue is allocated for it, and only then can be TXed. Therefore, it
+ * is placed into %iwl_mvm_tid_data.deferred_tx_frames, and a worker called
+ * %mvm->add_stream_wk later allocates the queues and TXes the deferred frames.
+ *
+ * For convenience, MGMT is considered as if it has TID=8, and go to the MGMT
+ * queues in the pool. If there is no longer a free MGMT queue to allocate, a
+ * queue will be allocated from the DATA pool instead. Since QoS NDPs can create
+ * a problem for aggregations, they too will use a MGMT queue.
+ *
+ * When adding a STA, a DATA queue is reserved for it so that it can TX from
+ * it. If no such free queue exists for reserving, the STA addition will fail.
+ *
+ * If the DATA queue pool gets exhausted, no new STA will be accepted, and if a
+ * new RA/TID comes in for an existing STA, one of the STA's queues will become
+ * shared and will serve more than the single TID (but always for the same RA!).
+ *
+ * When a RA/TID needs to become aggregated, no new queue is required to be
+ * allocated, only mark the queue as aggregated via the ADD_STA command. Note,
+ * however, that a shared queue cannot be aggregated, and only after the other
+ * TIDs become inactive and are removed - only then can the queue be
+ * reconfigured and become aggregated.
+ *
+ * When removing a station, its queues are returned to the pool for reuse. Here
+ * we also need to make sure that we are synced with the worker thread that TXes
+ * the deferred frames so we don't get into a situation where the queues are
+ * removed and then the worker puts deferred frames onto the released queues or
+ * tries to allocate new queues for a STA we don't need anymore.

+eBPF sample programs
+====================
+
+This directory contains a mini eBPF library, test stubs, verifier
+test-suite and examples for using eBPF.
+
+Build dependencies
+==================
+
+Compiling requires having installed:
+ * clang >= version 3.4.0
+ * llvm >= version 3.7.1
+
+Note that LLVM's tool 'llc' must support target 'bpf', list version
+and supported targets with command: ``llc --version``
+
+Kernel headers
+--------------
+
+There are usually dependencies to header files of the current kernel.
+To avoid installing devel kernel headers system wide, as a normal
+user, simply call::
+
+ make headers_install
+
+This will creates a local "usr/include" directory in the git/build top
+level directory, that the make system automatically pickup first.
+
+Compiling
+=========
+
+For building the BPF samples, issue the below command from the kernel
+top level directory::
+
+ make samples/bpf/
+
+Do notice the "/" slash after the directory name.
+
+It is also possible to call make from this directory. This will just
+hide the the invocation of make as above with the appended "/".
+
+Manually compiling LLVM with 'bpf' support
+------------------------------------------
+
+Since version 3.7.0, LLVM adds a proper LLVM backend target for the
+BPF bytecode architecture.
+
+By default llvm will build all non-experimental backends including bpf.
+To generate a smaller llc binary one can use::
+
+ -DLLVM_TARGETS_TO_BUILD="BPF"
+
+Quick sniplet for manually compiling LLVM and clang
+(build dependencies are cmake and gcc-c++)::
+
+ $ git clone http://llvm.org/git/llvm.git
+ $ cd llvm/tools
+ $ git clone --depth 1 http://llvm.org/git/clang.git
+ $ cd ..; mkdir build; cd build
+ $ cmake .. -DLLVM_TARGETS_TO_BUILD="BPF;X86"
+ $ make -j $(getconf _NPROCESSORS_ONLN)
+
+It is also possible to point make to the newly compiled 'llc' or
+'clang' command via redefining LLC or CLANG on the make command line::
+
+ make samples/bpf/ LLC=~/git/llvm/build/bin/llc CLANG=~/git/llvm/build/bin/clang
