Merge tag 'wireless-drivers-next-for-davem-2015-06-18' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
Major changes:

mwifiex:

* enhancements for AP mode: support verbose information in station
  dump command and also information about AP link.
* enable power save by default

brcmfmac:

* fix module reload issue for PCIe
* improving msgbuf protocol for PCIe devices
* rework .get_station() cfg80211 callback operation
* determine interface combinations upon device feature support

ath9k:

* ath9k_htc: add support of channel switch

wil6210:

* add modparam for bcast ring size
* support hidden SSID
* add per-MCS Rx stats
====================
