From: Sujith Manoharan <Sujith.Manoharan@xxxxxxxxxxx>
* Register the driver's maximum ampdu subframe limit to mac80211.
* Cleanup the target capabilities structure and fix an endian issue.
* Fix BTCOEX by sending a command to the target when the BT priority
changes.
* Bump the required firmware version to 1.1
