2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Felix Fietkau <nbd@xxxxxxxxxxx> This is a backport of upstream commit: e8c6342d989e241513baeba4b05a04b6b1f3bc8b 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. Signed-off-by: Felix Fietkau <nbd@xxxxxxxxxxx> Signed-off-by: Luis R.
