​Do the NICs eventually pick up carrier status if you leave it after boot?
Could it just be slow picking up status changes?  We had a couple em(4) or
igb(4) (forget now) NICs that were like that.  Took a good minute after
boot before the NIC was finished initialising and detected the link.

If that's the case, and you don't mind the wait (and want to make sure
networking is working once the boot is complete), you can use the netwait_*
options in /etc/rc.conf.  That will pause the boot process until either the
network link status changes to up, and/or you can ping the default gateway
or any other IP on the network.

Worked for us.  Might work for you.​
