This series add changes to support offload of connection tracking across multiple zones. Previously the driver only supported offloading of a single goto_chain, spanning a single zone. This was implemented by merging a pre_ct rule, post_ct rule and the nft rule. This series provides updates to let the original post_ct rule act as the new pre_ct rule for a next set of merges if it contains another goto and conntrack action. In pseudo-tc rule format this adds support for: ingress chain 0 proto ip flower action ct zone 1 pipe action goto 1 ingress chain 1 proto ip flower ct_state +tr+new ct_zone 1 action ct_clear pipe action ct zone 2 pipe action goto 2 ingress chain 1 proto ip flower ct_state +tr+est ct_zone 1 action ct_clear pipe action ct zone 2 pipe action goto 2 ingress chain 2 proto ip flower ct_state +tr+new ct_zone 2 action mirred egress redirect dev ... ingress chain 2 proto ip flower ct_state +tr+est ct_zone 2 action mirred egress redirect dev ... This can continue for up to a maximum of 4 zone recirculations. The first few patches are some smaller preparation patches while the last one introduces the functionality.
