This change converts the "I already have an address" check to be a
"I'm up" which are two different things.  dhclient leaves the
interface up when it exits, even if it can't get an address.  I think
that might cause a lot of problems for people.  I originally had this
test in pccard_ether, but changed it to checking for netmask because
roving from network to network didn't work without it on my laptop
with multiple network interfaces.

I think it will have issues on more than just these naughty drivers.
