Subject: [PATCH net-next V2 1/8] net: fec: stop the "rcv is not +last, " error messages
Date: Fri, 5 Feb 2016 14:52:43 -0700 [thread overview]
Message-ID: <1454709170-19527-2-git-send-email-troy.kisky@boundarydevices.com> (raw)
In-Reply-To: <1454709170-19527-1-git-send-email-troy.kisky@boundarydevices.com>
Setting the FTRL register will stop the fec from
trying to use multiple receive buffers.
