Hmmm....I made that change for a reason.  Waiting for autonegotiation
to finish on a tsec with no link was quite tiresome.  If you've hooked
up the 4th tsec, and try to boot, you end up waiting for *three* tsecs
to timeout.  If dhcp fails because the link isn't up you can always
try again, or add a delay before dhcp starts so that the link is up.

I'm open to other suggestions, but I really don't want to go back to
the old behavior.
