From: Felix Fietkau <nbd@xxxxxxxxxxx> This patch fixes a bug in ath9k's tx status check, which caused mac80211 to consider regularly transmitted unicast frames as un-acked. When checking the ts_status field for errors, it needs to be masked with ATH9K_TXERR_FILT, because this field also contains other fields like ATH9K_TX_ACKED. Without this patch, AP mode is pretty much unusable, as hostapd checks the ACK status for the frames that it injects.
