Happened to me once needed to set the the speed of the nic card in
rc.conf can not remember how to do it but it is in the man rc.conf page
and solved my similar problem. Looks something like this if i can recall
ifconfig_xl0="inet 22.214.171.124 something about manually setting the
speed and mode of the card "
for me it had to do with the card not negotiating it parameters properly
and i had to beat it into submission with manual overrides. glanced
through the rc.conf man page but it is to long for me deal with right
now the setting are in there somewhere.
