Merge tag 'wireless-drivers-next-for-davem-2015-04-01' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

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
