FreeBSD 7.1 Breaks re and rl Network Interface Drivers

[Walter Venable]

FreeBSD 7.1 upgrade broke my network access, machine is totally
offline (powered-on and I can play inside it at the terminal, but
absolutely 0 network access):
This happened AFTER make kernel but BEFORE make installworld.  I think
this implies it's a kernel driver issue.

thread on the issue, the rl driver has also been reported broken).
