Kalle Valo says:
====================
Major changes:
ath9k:
* add Active Interference Cancellation, a method implemented in the HW
to counter WLAN RX > sensitivity degradation when BT is transmitting
at the same time. This feature is supported by cards like WB222
based on AR9462.
iwlwifi:
* Location Aware Regulatory was added by Arik
* 8000 device family work
* update to the BT Coex firmware API
brmcfmac:
* add new BCM43455 and BCM43457 SDIO device support
* add new BCM43430 SDIO device support
wil6210:
* take care of AP bridging
* fix NAPI behavior
* found approach to achieve 4*n+2 alignment of Rx frames
rt2x00:
* add new rt2800usb device DWA 130
rtlwifi:
* add USB ID for D-Link DWA-131
* add USB ID ASUS N10 WiFi dongle
mwifiex:
* throughput enhancements
