Subject: [PATCH] 3c59x: fix duplex configuration
Date: Thu, 9 Aug 2007 10:57:54 +0200 [thread overview]
Message-ID: <20070809085754.GA29945@bayes.mathematik.tu-chemnitz.de> (raw)
A special sequence of ifconfig up/down and plug/unplug the cable
can break the duplex configuration of the driver.
Setting
vp->mii.full_duplex = vp->full_duplex
in vortex_up should fix this.
