nd6_resolve: XXX: incorrect nd6 information

Hi misc@,

I have a VMM host running 7.8, including the recent nd6 patch.

It was stable for about 10 days or so, and after launching another VM I
started getting this:
nd6_resolve: XXX: incorrect nd6 information

vmctl console was unresponsive on them as well.

Before it died altogether, I was seeing erratic network behavior.

It's possible this didn't start till I launched a Debian VM, but I am
not sure.

VMs are all IPv6 and route through the host via the tap interfaces.
There's 7 total tap interfaces with 6 VMs running. I cut it down to 2 or
3 VMs running and was still having problems.

I finally rebooted the server. Not sure if this will continue or not.
