From: Vinith Kumar R <quic_vinithku@xxxxxxxxxxx>
Currently Tx completion for few exception packets are received from
firmware and the tx status updated to mac80211. The tx status values of
HAL_WBM_REL_HTT_TX_COMP_STATUS_DROP and HAL_WBM_REL_HTT_TX_COMP_STATUS_TTL
are considered as tx failure and reported as tx failure to mac80211.
But these failure status is due to internal firmware tx drop and these
packets were not tried to transmit in the air.
In case of mesh this invalid tx status report might trigger mpath broken
issue due to increase in mpath fail average.
So do not report these tx status as tx failure instead free the skb
by calling ieee80211_free_txskb(), and that will be accounted as dropped
frame.
