- Subject: [PATCH] netfilter: nf_flow_table: fix priv pointer for netdev hook
- The offload ip hook expects a pointer to the flowtable, not to the
- rhashtable. Since the rhashtable is the first member, this is safe for
- the moment, but breaks as soon as the structure layout changes
- Signed-off-by: Felix Fietkau <nbd@nbd.name>
