From: Artur Molchanov <[email protected]>
Fixes: c5136b15ea36 ("netfilter: bridge: add and use br_nf_hook_thresh")
Problem:
br_nf_pre_routing_finish() calls itself instead of
br_nf_pre_routing_finish_bridge().
Due to this bug reverse path filter drops packets that moving through
bridge interface.
User impact:
Local docker containers with bridge network can not communicate with
each other.
