Log Message:
Pull up following revision(s) (requested by christos in ticket #206):
        sys/external/bsd/ipf/netinet/ip_fil_netbsd.c: 1.24-1.26
Fix ipf failing to sent TCP RST's on link-local interfaces by stuffing
the scope KAME style before calling the routing routines instead of after.

>From Edgar Fuss:
ipf's return-icmp doesn't work when the packet matched by the rule is
directed at a link local address. The problem is that
ipf_send_icmp_err() calls ipf_ifpaddr() to find an address of the
interface in question, but that routine discards link local addresses.
I guess the best fix is to simply use the destination address instead if
it is link local, i.e. treat the rule as if return-icmp-as-dest was
given in this case.

use the scoping functions (JINMEI, Tatuya)
