Ah. That makes sense when I finally think about it.
I'm trying to move the DHCP (client currently but eventually server as
well) away from using PF_PACKET to something influenced by iptables
filters.
Current attempts are using -j QUEUE to receive the packets. I need to
be able to re-inject a packet to a different destination (from the input
table back out to the output table) back into netfilter.
I could probably receive through netfilter and send through SOCK_RAW? At
leat that might prevent the flooding problems I'm having.
