Message-Id: <E1X0Xvg-0001My-Mk@rmk-PC.arm.linux.org.uk> Date: Fri, 27 Jun 2014 16:19:08 +0100 From: Russell King <rmk+kernel@....linux.org.uk> To: linux-arm-kernel@...ts.infradead.org, netdev@...r.kernel.org Cc: Fugang Duan <B38611@...escale.com> Subject: [PATCH CFT 03/30] net: fec: fix ethtool set_pauseparam duplex bug Setting the pause parameters causes a running network interface to be restarted. However, the restart forces the FEC into half-duplex mode, whether or not the remote end is in half-duplex mode. Misconfigured duplex mode is a known source of problems on a link. Fix this by always preserving the duplex mode on configuration changes.
