Subject: e1000: allow ethtool to see link status when down
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ca6efb7d6c9336acda2e7b76a39b59bbfe77ec13;p=linux-beck.git

e1000: allow ethtool to see link status when down

By reading the MAC status register we can detect whether the MAC has
seen the PHY see link. This allows us to show the link properties before
the device is up in ethtool.
