        I don't know if it's relevant or not to your problem, but
loopback, by default, is not multicast-capable, and it also does
not have a MAC address (used to generate the client ID). And, of
course, there isn't much use in running DHCP on loopback. :-)
        "ifconfig lo multicast" appears to set the interface flag,
though I don't know if that means it works properly. The client
I have fails on "lo" with error messages "doesn't support
hardware type 772", "failed to get hardware address", and
"failed to get a DUID" (in that order).
        You can use "strace" to find out specifically what it did,
but my guess is that it's a bug in the application.
