I quicly look into our ifconfig.c and sadly it seems the rejection is 
in our stack, not in our ifconfig tool.
That's exactly why I don't like userland tools features dependencies.
I guess we may try to better integrate David Enderson's DHCP code 
deeper into the stack.
To me, DHCP support is as mandatory as ARP these days...
I doesn't mean we won't have a command line tool (dhconfig, to be BONE 
compatible?) to control stack's DHCP behavior.
