[src/trunk]: src/sys Merge ipsec4_input and ipsec6_input into ipsec_ip_input....
details: https://anonhg.NetBSD.org/src/rev/665f5e40243c
branches: trunk
changeset: 361839:665f5e40243c
user: maxv <maxv%NetBSD.org@localhost>

description:
Merge ipsec4_input and ipsec6_input into ipsec_ip_input. Make the argument
a bool for clarity. Optimize the function: if M_CANFASTFWD is not there
(because already removed by the firewall) leave now.
Makes it easier to see that M_CANFASTFWD is not removed on IPv6.
