patch review for kern/146534

[Earl Lapus]

Hi,

I submitted a patch which fixes the problem described in the PR and it
also retains this
(http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet6/icmp6.c.diff?r1=1.118;r2=1.119;f=h)
fix.

I also ran the TAHI (tool version REL_3_3_0; test program version
V6LC_4_0_5) phase 2 NDP test scripts and they all passed.

I'm not 100% sure that the patch is correct. The code used to check if
the original destination address is an anycast address is a bit
redundant. I hope someone from the list can have a look at it.

Cheers!
Earl
