Merge tag 'wireless-drivers-for-davem-2016-01-29' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers

Kalle Valo says:

====================
iwlwifi

* Fix support for 3168 device:
  * NVM version
  * firmware file name
  * device IDs
* Fix a compilation warning in dvm calibration code
* Fix the TPC (reduced Tx Power) code. This fixes performance issues
* Add device IDs for 8265

rtx2x00

* fix monitor mode regression dating back to 4.1

brcmfmac

* fix sdio initialisation related crash

rtlwifi

* rtl8821ae: Fix 5G failure when EEPROM is incorrectly encoded

ath9k

* ignore eeprom magic mismatch on flash based devices
====================
