Remove the global flow_block_cb_list, replace it by per-driver list
of flow block objects. This will make it easier later on to support
for policy hardware offload of multiple subsystems.
Suggested-by: Jiri Pirko <j...@resnulli.us>
Signed-off-by: Pablo Neira Ayuso <pa...@netfilter.org>
---
v2: new patch, no previous v1.
Introduce per-driver list of flow blocks as Jiri requested.
