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
====================
