Subject: [PATCH net-next] em_ipset: use dev_net() accessor

From: Stephen Hemminger <[email-masked]>
Date: Wed, 16 Oct 2013 17:29:34 -0700

Randy found that if network namespace not enabled then
nd_net does not exist and would cause compilation failure.

This is handled correctly by using the dev_net() macro.
