Title:
Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.144 or
later causes 'invalid argument' error

Bug description:
Setting net.ipv4.neigh.default.gc_thresh1/2/3 on the 3.13.0-96-generic
kernel and below worked fine using the following:
$ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
128
As of 3.13.0-97-generic, though, it no longer works as expected:
$ sudo /sbin/sysctl -w net.ipv4.neigh.default.gc_thresh1=128
error: "Invalid argument" setting key "net.ipv4.neigh.default.gc_thresh1"
There are two potentially related revisions in the -97 release -
http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
backport-trusty&id=563cf19389d8e999e69d6c94995966aeaf7c3a08 and
http://kernel.ubuntu.com/git/ubuntu/ubuntu-precise.git/commit/?h=lts-
backport-trusty&id=7b82096b0ebc9bf487b390fe970d66ffa5a5774e.
The expected behavior is that changing neighbor table settings works
using 'sysctl -w' with the same values as before the -97 kernel.
