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