From c97c96a77b54729f31a5e7b0209d87f314d1d8fe Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Mon, 7 Mar 2016 20:56:07 +0100 Subject: [PATCH] man: ip-neighbour.8: Document all known nud states Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1276661 Upstream Status: iproute2.git commit 948acfed23e5e commit 948acfed23e5e314fe0f4f863da0368f56645d32 Author: Phil Sutter Date: Fri Mar 4 20:07:20 2016 +0100 man: ip-neighbour.8: Document all known nud states Not sure how useful they are in practice, but as 'ip neigh' supports setting them all, they deserve to be described as well. While at it, also add a missing layer of indentation to the subordinate nud state list.
