-Subject: [PATCH 065/102] net: mediatek: fix stop and wakeup of queue
-
-The driver supports 2 MACs. Both run on the same DMA ring. If we go
-above/below the TX rings thershold value, we always need to wake/stop
-the queu of both devices. Not doing to can cause TX stalls and packet
-drops on one of the devices.
