Merge ath-next from ath.git. Major changes in ath10k:
* add support for qca99x0 family of devices
* improve performance of tx_lock
* add support for raw mode (802.11 frame format) and software crypto
engine enabled via a module parameter
wil6210:
* implement TSO support
* support bootloader v1 and onwards
