From 39971554d3469b48154f34257ad4a35081b7ee40 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 10 Jan 2008 22:37:16 -0800 Subject: [PATCH] [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".
