Subject: [PATCH net-next 01/40] net: fec: stop the "rcv is not +last, " error messages
Date: Thu, 28 Jan 2016 14:25:25 -0700	[thread overview]
Message-ID: <1454016364-30985-2-git-send-email-troy.kisky@boundarydevices.com> (raw)
In-Reply-To: <1454016364-30985-1-git-send-email-troy.kisky@boundarydevices.com>

Setting the FTRL register will stop the fec from
trying to use multiple receive buffers.
