Yes, probably a bug introduced by arp-v2, I will investigate and
get back to you.

Something seems to be wrong with IPv6 neighbor discovery.

FreeBSD lorvorc.mips.inka.de 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Sat Dec =
20 17:46:35 CET 2008 =
naddy@lorvorc.mips.inka.de:/usr/obj/usr/src/sys/GENERIC  amd64

This box is on a network that has IPv6.  No exciting configuration,
just ipv6_enable=3DYES and ipv6_defaultrouter and ipv6_ifconfig_nfe0
for a manually configured address.  IPv6 with other hosts on the
network and beyond works.

However, clearing the NDP cache (ndp -c) kills IPv6 connectivity.
The cache remains empty.  tcpdump shows that neighbor solicitations
are sent and advertisement received, but these replies seem to be
ignored.  ndp -a shows that no entries are added to the cache.

This is a new problem.  Fallout from arp-v2?
