Subject: [PATCH 1/2 net] r6040: invoke phy_{start,stop} when appropriate
Date: Fri, 7 Oct 2011 11:40:17 +0200 [thread overview]
Message-ID: <201110071140.17299.florian@openwrt.org> (raw)
Joe reported to me that right after a bring up of a r6040 interface
the ethtool output had no consistent output with respect to link duplex
and speed. Fix this by adding a missing phy_start call in r6040_up and
conversely a phy_stop call in r6040_down to properly initialize phy states.
