When an RX block-ack session times out, the firmware, which offloads RX reordering but not the BA session negotiation, stops the session but doesn't send a DELBA. This causes the the session to remain active in the remote device, so no more BA sessions will be established, causing a severe throughput degradation due to the lack of aggregation.
Use the new ieee80211_rx_ba_timer_expired API when the ba session timer expires, since this will tear down the ba session and also send a delba.
The previous API used is intended for drivers that offload the addba/delba negotiation, but not the rx reordering, while our driver does the opposite.
This patch depends on "mac80211: add api to start ba session timer expired flow".
