netfilter: netns nf_conntrack: per-netns conntrack hash
* make per-netns conntrack hash Other solution is to add ->ct_net pointer to tuplehashes and still has one hash, I tried that it's ugly and requires more code deep down in protocol modules et al. * propagate netns pointer to where needed, e. g. to conntrack iterators.
