2.6.34-stable review patch. If anyone has any objections, please let us know.

------------------


From: Ben Greear <greearb@xxxxxxxxxxxxxxx>

[ Upstream commit c736eefadb71a01a5e61e0de700f28f6952b4444 ]

With conn-track zones and probably with different network
namespaces, the netfilter logic needs to be re-calculated
on packet receive. If the netfilter logic is not reset,
it will not be recalculated properly. This patch adds
the nf_reset logic to dev_forward_skb.
