Kalle Valo says:

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

* bug fix for TDLS
* fixes and cleanups in scan
* support of several scan plans
* improvements in FTM
* fixes in FW API
* improvements in the failure paths when the bus is dead
* other various small things here and there

ath10k

* add QCA9377 support
* fw_stats support for 10.4 firmware

ath6kl

* report antenna configuration to user space
* implement ethtool stats

ssb

* add Kconfig SSB_HOST_SOC for compiling SoC related code
* move functions specific to SoC hosted bus to separated file
* pick PCMCIA host code support from b43 driver
