Thanks for the reference.
Man mii-tool says this utility does not cover 1G nics and is obsolete.
It recommends ethtool instead. '/sbin/ethtool eth0' says that the ic is
running at 100mb/s although it has 1G/s capability. So I am curious why
the nic does not initialize to 1G or light up the port led on the 1G
switch.
