Well, on my systems I have fwip0 reported as an interface.
It does not advertise carrier, so dhcpcd will automatically try and get 
an IP address and fail. This normally isn't an issue, but I'm looking at 
getting dhcpcd to background when after getting an IP or no interface 
has a carrier. NetBSD is my only system where fwip0 is visible by 
default, so I'd like to get something done, either in dhcpcd or in NetBSD.
