-Subject: [PATCH] wifi: ath11k: Don't drop tx_status when peer cannot be found
-
-When a station idles for a long time, hostapd will try to send a QoS Null
-frame to the station as "poll". NL80211_CMD_PROBE_CLIENT is used for this
-purpose. And the skb will be added to ack_status_frame - waiting for a
-completion via ieee80211_report_ack_skb().
-
-But when the peer was already removed before the tx_complete arrives, the
-peer will be missing. And when using dev_kfree_skb_any (instead of going
-through mac80211), the entry will stay inside ack_status_frames. This IDR
-will therefore run full after 8K request were generated for such clients.
-At this point, the access point will then just stall and not allow any new
-clients because idr_alloc() for ack_status_frame will fail.
-
-ieee80211_free_txskb() on the other hand will (when required) call
-ieee80211_report_ack_skb() and make sure that (when required) remove the
-entry from the ack_status_frame.
-
-Tested-on: IPQ6018 hw1.0 WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1

-Fixes: 94739d45c388 ("ath11k: switch to using ieee80211_tx_status_ext()")
