It says you may transmit as 0.0.0.0 for those special cases but nowhere
does it say you should respond to normal traffic on that address. Thats
what dhcpcd causes in its current mode of operation.

DHCPD needs to use SOCK_PACKET. Now that we have the BPF filter on
SOCK_PACKET this can be done very cleanly
