From: Malcolm Priestley <tvboxspy@gmail.com> commit 9dd631fa99dc0a0dfbd191173bf355ba30ea786a upstream. The driver reporting IEEE80211_TX_STAT_ACK is not being handled correctly. The driver should only report on TSR_TMO flag is not set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK is being requested.
