From: Felix Fietkau <nbd@openwrt.org>
commit 5b479a076de091590423a9e6dfc2584126b28761 upstream.
My previous change added in:
commit 815833e7ecf0b9a017315cae6aef4d7cd9517681 ath9k: fix tx status reporting
was not checking all possible tx error conditions. This could possibly lead to throughput issues due to slow rate control adaption or missed retransmissions of failed A-MPDU frames.
This patch adds a mask for all possible error conditions and uses it in the xmit ok check.
