prototypes for the IPv6 ECN ingress/egress functions in sys/netinet/ip_ecn.h, inside an #ifdef INET6 wrapper. So, wrap sys/netipsec ocurrences of #include <netinet6/ip6_ecn.h> in #ifdef __FreeBSD__/#endif, until both camps can agree on this teensy little piece of namespace. Affects: ipsec_output.c xform_ah.c xform_esp.c xform_ipip.c
