Subject: qtnfmac: modify full Tx queue error reporting
From: Sergey Matyukevich <sergey.matyukevich.os@xxxxxxxxxxxxx>
[ Upstream commit e9931f984dd1e80adb3b5e095ef175fe383bc92d ]
Under heavy load it is normal that h/w Tx queue is almost full all the time
and reclaim should be done before transmitting next packet. Warning still
should be reported as well as s/w Tx queues should be stopped in the
case when reclaim failed.
