History
Dag-Erling Smørgrav 1b968362aa Add support for stealth forwarding (forwarding packets without touching 
their ttl). This can be used - in combination with the proper ipfw
incantations - to make a firewall or router invisible to traceroute
and other exploration tools.

This behaviour is controlled by a sysctl variable (net.inet.ip.stealth)
and hidden behind a kernel option (IPSTEALTH).
