Hello,

The attached patch contains the following 3 commits that I brought from OpenBSD:

1. pf: use IN6_IS_SCOPE_EMBED to check kernel-internal form addresses
2. pf: Always skip "urpf-failed" test for IPv6 link local addresses
3. pf: Make pf_print_host() print IPv6 addresses correctly

The second commit fixes the "uprf-failed" issue on IPv6 that I shared on the mailing list some time ago [1].  With this fix, the "urpf-failed" rule can just be enabled on both IPv4 and IPv6.

Credit to Marcin Wisnicki, who pointed out the problem and gave fixes to it [2].
