It could be a configuration error. The packet never leaves your
machine for your own address anyway. Can you look at the back of the
card and see any lights flashing in time with the ping packets? Does
the entry for the card in /proc/interrupts increase? Can another
machine ping yours? Does "tcpdump" show any network traffic? Does
/proc/net/arp show any other addresses when you try to ping them?

This could be because it's trying to look up the name in DNS. How
about "netstat -rn"?
Is 255.255.0.0 the correct netmask for your network? I don't think
there are many class B networks around.

I think this is just what the SMC Ultra card does. Have a look at
/proc/ioports.

The module usually won't load if it's incompatible.
