Subject: [PATCH v2 0/3] Handle stuck TX queue bug in AT8030 PHY
Date: Wed, 18 Jun 2014 11:01:40 +0200	[thread overview]
Message-ID: <1403082103-23709-1-git-send-email-zonque@gmail.com> (raw)

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
