When I run ifconfig I get:
ifconfig eth0 media 10baseT
port: SIOCSIFMAP: Operation not supported

The man page for ifconfig does say that not all
drivers support all media types or the media operation
at all.  Is there another way to change the speed
setting using the eepro100 driver?

The connections are going from our server to a Cisco
catalyst 6509 switch.  All ethernet, so no transitions
to another encapsulation type like on a dsl line.  I
think the MTU is a good direction to go in, but I
wonder why the service provider thinks the errors have
to do with the speed setting on the server.  Any
ideas?
