Log message:
support configuring BIOCSFILDROP with tcpdump.
this allows tcpdump to be used a quick and dirty firewall. it also
looks like an amazing foot-gun, so be careful.
for example `tcpdump -B drop -i ix1 udp and port 7` lets you
completely drop discard packets in the hardware interrupt handler.
