* remove support for -9.ucode
* new statitics API
* rate control improvements

ath9k:

* add per-vif TX power capability
* BT coexistance fixes

ath10k:

* qca6174: enable STA transmit beamforming (TxBF) support
* disable multi-vif power save by default

bcma:

* enable support for PCIe Gen 2 host devices
