mac80211: Stop BA session event from device
Some devices support BT/WLAN co-existence algorigthms. In order not to harm the system performance and user experience, the device requests not to allow any RX BA session and tear down existing RX BA sessions based on system constraints such as periodic BT activity that needs to limit WLAN activity (eg.SCO or A2DP). In such cases, the intention is to limit the duration of the RX PPDU and therefore prevent the peer device to use A-MPDU aggregation. Adding ieee80211_stop_rx_ba_session() callback that can be used by the driver to stop existing BA sessions. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: John W.
