Subject: [PATCH net-2.6.25][NEIGH]: Add a comment describing what a NUD stands
for.
When I studied the neighbor code I puzzled over what
the NUD can mean for quite a long time.
Finally I asked Alexey and he said that this was smth
like "neighbor unreachability detection".
Does it worth adding a comment helping future developers
understand what's going on?
