+Subject: [PATCH 092/102] net-next: mediatek: remove superfluous queue wake up
+ call
+
+The code checks if the queue should be stopped because we are below the
+threshold of free descriptors only to check if it should be started again.
+If we do end up in a state where we are at the threshold limit, it makes
+more sense to just stop the queue and wait for the next IRQ to trigger the
+TX housekeeping again. There is no rush in enqueuing the next packet, it
+needs to wait for all the others in the queue to be dispatched first
+anyway.
