   3 Subject: [PATCH] netfilter: nf_flow_table: fix priv pointer for netdev hook
   4
   5 The offload ip hook expects a pointer to the flowtable, not to the
   6 rhashtable. Since the rhashtable is the first member, this is safe for
   7 the moment, but breaks as soon as the structure layout changes
