dhcpcd CAN work on IEEE FireWire interfaces.

However, BPF does not appear to operate on these, so we report the error
and continue.
When BPF supports FireWire for DHCP, dhcpcd will magically start to work.

 .It Dv FAIL
-dhcpcd failed to contact any DHCP servers or use an old lease.
+dhcpcd failed to operate on the interface.
+This normally happens when dhcpcd does not support the raw interface, which

 dhcpcd received an OFFER from a DHCP server but will not configure the
 interface.
