Major changes: 

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
 
 ath9k:
 
 * add fast-xmit support
 
 wil6210:
 
 * implement TSO support
 * support bootloader v1 and onwards
 
 iwlwifi:
 
 * Deprecate -10.ucode
 * Clean ups towards multiple Rx queues
 * Add support for longer CMD IDs. This will be required by new
   firmwares since we are getting close to the u8 limit.
 * bugfixes for the D0i3 power state
 * Add basic support for FTM
 * polish the Miracast operation
 * fix a few power consumption issues
 * scan cleanup
 * fixes for D0i3 system state
 * add paging for devices that support it
 * add again the new RBD allocation model
 * add more options to the firmware debug system
 * add support for frag SKBs in Tx
