Merge tag 'wireless-drivers-next-for-davem-2015-08-19' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says:
====================
Major changes:
ath10k:
* add support for qca99x0 family of devices
* improve performance of tx_lock
* add support for raw mode (802.11 frame format) and software crypto
engine enabled via a module parameter
ath9k:
* add fast-xmit support
wil6210:
* implement TSO support
* support bootloader v1 and onwards
iwlwifi:
* Deprecate -10.ucode
* Clean ups towards multiple Rx queues
* Add support for longer CMD IDs. This will be required by new
firmwares since we are getting close to the u8 limit.
* bugfixes for the D0i3 power state
* Add basic support for FTM
* polish the Miracast operation
* fix a few power consumption issues
* scan cleanup
* fixes for D0i3 system state
* add paging for devices that support it
* add again the new RBD allocation model
* add more options to the firmware debug system
* add support for frag SKBs in Tx
====================

+Netdev private dataroom for 6lowpan interfaces:
+
+All 6lowpan able net devices, means all interfaces with ARPHRD_6LOWPAN,
+must have "struct lowpan_priv" placed at beginning of netdev_priv.
+
+The priv_size of each interface should be calculate by:
+
+ dev->priv_size = LOWPAN_PRIV_SIZE(LL_6LOWPAN_PRIV_DATA);
+
+Where LL_PRIV_6LOWPAN_DATA is sizeof linklayer 6lowpan private data struct.
+To access the LL_PRIV_6LOWPAN_DATA structure you can cast:
+
+ lowpan_priv(dev)-priv;
+
+to your LL_6LOWPAN_PRIV_DATA structure.
+
+Before registering the lowpan netdev interface you must run:
+
+ lowpan_netdev_setup(dev, LOWPAN_LLTYPE_FOOBAR);
+
+wheres LOWPAN_LLTYPE_FOOBAR is a define for your 6LoWPAN linklayer type of
+enum lowpan_lltypes.
+
+Example to evaluate the private usually you can do:
+
+static inline sturct lowpan_priv_foobar *
+lowpan_foobar_priv(struct net_device *dev)
+{
+ return (sturct lowpan_priv_foobar *)lowpan_priv(dev)->priv;
+}
+
+switch (dev->type) {
+case ARPHRD_6LOWPAN:
+ lowpan_priv = lowpan_priv(dev);
+ /* do great stuff which is ARPHRD_6LOWPAN related */
+ switch (lowpan_priv->lltype) {
+ case LOWPAN_LLTYPE_FOOBAR:
+ /* do 802.15.4 6LoWPAN handling here */
+ lowpan_foobar_priv(dev)->bar = foo;
+ break;
+ ...
+ }
+ break;
+...
+}
+
+In case of generic 6lowpan branch ("net/6lowpan") you can remove the check
+on ARPHRD_6LOWPAN, because you can be sure that these function are called
+by ARPHRD_6LOWPAN interfaces.

+The VXLAN protocol is a tunnelling protocol designed to solve the
+problem of limited VLAN IDs (4096) in IEEE 802.1q. With VXLAN the
+size of the identifier is expanded to 24 bits (16777216).
-It is a draft RFC standard, that is implemented by Cisco Nexus,

-destination port (still not standardized by IANA).
-This document describes the Linux kernel tunnel device,

+VXLAN is described by IETF RFC 7348, and has been implemented by a
+number of vendors. The protocol runs over UDP using a single
+destination port. This document describes the Linux kernel tunnel
+device, there is also a separate implementation of VXLAN for
+Openvswitch.
-Unlike most tunnels, a VXLAN is a 1 to N network, not just point

-of the other end, in a manner similar to a learning bridge, or the
-forwarding entries can be configured statically.

- # ip li add vxlan0 type vxlan id 42 group 239.1.1.1 dev eth1
+ # ip link add vxlan0 type vxlan id 42 group 239.1.1.1 dev eth1 dstport 4789

+This creates a new device named vxlan0. The device uses the multicast
+group 239.1.1.1 over eth1 to handle traffic for which there is no
+entry in the forwarding table. The destination port number is set to
+the IANA-assigned value of 4789. The Linux implementation of VXLAN
+pre-dates the IANA's selection of a standard destination port number
+and uses the Linux-selected value by default to maintain backwards
+compatibility.
2. Delete vxlan device

+ *
+ * The CTRLA register provides us with the amount of data
+ * already read from the source for the current child
+ * descriptor. So we can compute a more accurate residue by also
+ * removing the number of bytes corresponding to this amount of
+ * data.
+ *
+ * However, the DSCR and CTRLA registers cannot be read both
+ * atomically. Hence a race condition may occur: the first read
+ * register may refer to one child descriptor whereas the second
+ * read may refer to a later child descriptor in the list
+ * because of the DMA transfer progression inbetween the two
+ * reads.
+ *
+ * One solution could have been to pause the DMA transfer, read
+ * the DSCR and CTRLA then resume the DMA transfer. Nonetheless,
+ * this approach presents some drawbacks:
+ * - If the DMA transfer is paused, RX overruns or TX underruns
+ * are more likey to occur depending on the system latency.
+ * Taking the USART driver as an example, it uses a cyclic DMA
+ * transfer to read data from the Receive Holding Register
+ * (RHR) to avoid RX overruns since the RHR is not protected
+ * by any FIFO on most Atmel SoCs. So pausing the DMA transfer
+ * to compute the residue would break the USART driver design.
+ * - The atc_pause() function masks interrupts but we'd rather
+ * avoid to do so for system latency purpose.
+ *
+ * Then we'd rather use another solution: the DSCR is read a
+ * first time, the CTRLA is read in turn, next the DSCR is read
+ * a second time. If the two consecutive read values of the DSCR
+ * are the same then we assume both refers to the very same
+ * child descriptor as well as the CTRLA value read inbetween
+ * does. For cyclic tranfers, the assumption is that a full loop
+ * is "not so fast".
+ * If the two DSCR values are different, we read again the CTRLA
+ * then the DSCR till two consecutive read values from DSCR are
+ * equal or till the maxium trials is reach.
+ * This algorithm is very unlikely not to find a stable value for

+ Support for IPv6 Identifier Locator Addressing (ILA).
+
+ ILA is a mechanism to do network virtualization without
+ encapsulation. The basic concept of ILA is that we split an
+ IPv6 address into a 64 bit locator and 64 bit identifier. The
+ identifier is the identity of an entity in communication
+ ("who") and the locator expresses the location of the
+ entity ("where").
+
+ ILA can be configured using the "encap ila" option with
+ "ip -6 route" command. ILA is described in
+ https://tools.ietf.org/html/draft-herbert-nvo3-ila-00.
+
+ If unsure, say N.
