*sigh* You can't set a mode that the NIC doesn't support. You have
a 10Mbps-only NIC (3c900/3c900B). These NICs do _NOT_ support
NWAY autoneg: 10baseT mode is implemented using a non-NWAY
transceiver which doesn't do autonegotiation. If you do
"ifconfig -m xl0" and 'auto' doesn't show up as one of the
supported modes, autoselect won't work.
If you want to do full duplex with this NIC, you will need to
manually set both ends of the link to do it. You can do this with
"ifconfig xl0 media 10baseT/UTP mediaopt full-duplex" on the NIC,
but you'll need to manually configure the switch via its management
interface to set the port with the xl0 link to full duplex as well.
If your switch is not managed and doesn't allow you to manually
configure the port settings, then you're out of luck. You'll just
have to live with half duplex mode.
