Subject: wlcore: Add RX_BA_WIN_SIZE_CHANGE_EVENT event
From: Maxim Altshul <[email protected]>
commit e7ee74b56f23ba447d3124f2eccc32033cca501d upstream.
This event is used by the Firmware to limit the RX BA win size for a specific link.
The event handler updates the new size in the mac's sta->sta struct.
BA sessions opened for that link will use the new restricted win_size. This limitation remains until a new update is received or until the link is closed.
