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 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
