Subject: [PATCH 4.14 11/89] staging: vt6656: Fix false Tx excessive retries reporting.
From: Malcolm Priestley <tvboxspy@...il.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.
