Subject: [PATCH 8/11 net-2.6.26] [NETNS]: Process netfilter hooks in initial namespace only.

There were no packets in the namespace other than initial previously. This
will be changed in the neareast future. Netfilters are not namespace aware
and should be processed in the initial namespace only for now.
