From: Yoshihiro Shimoda Date: Wed, 06 Jul 2011 06:33:51 +0000 Subject: [PATCH 1/2] net: sh_eth: fix cannot work half-duplex mode Message-Id: <4E1401CF.4080804@renesas.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: davem@davemloft.net Cc: netdev@vger.kernel.org, SH-Linux When link was down, the bit of DM in ECMR was always set. So, we could not use half-duplex mode on the controller.
