Can you add support for BQL (netdev_sent_queue/netdev_completed_queue) to limit the queue size to the minimum? I also noticed that your tx_lock() prevents you from concurrently running sun8i_emac_complete_xmit() and sun8i_emac_xmit(). Is that necessary? I'd think that you can find a way to make them work concurrently.
