Cover letter [PATCH v2 0/3] Handle stuck TX queue bug in AT8030 PHY

These three small patches circument a hardware bug in AT8030 PHYs that leads to stuck TX FIFO queues when the link goes away while there are pending patches in der outbound queue. This bug has been confirmed by the vendor, and their only proposed fix is to apply a hardware reset every time the link goes down.

Thanks,
Daniel
