Subject: [PATCH] net: ethernet: mtk_eth_soc: remove unnecessary TX queue stops
 | 
						|
 | 
						|
When running short on descriptors, only stop the queue for the netdev that
 | 
						|
tx was attempted for. By the time something tries to send on the other
 | 
						|
netdev, the ring might have some more room already.
