    Subject[120/151] ath9k: fix tx status reporting
    2.6.32-stable review patch.  If anyone has any objections, please let us know.


    From: Felix Fietkau <>

    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.
