Forgot to add:
This issue ONLY happens when using DHCP.
Statically assigning the IP address works fine; fxp0 goes down once,
up once, then stays up indefinitely.
I also tested network I/O in the statically-assigned scenario. Pinging
the box from another machine on the LAN:
$ ping 192.168.1.192
PING 192.168.1.192 (192.168.1.192): 56 data bytes
