nfp: flower: add support for multi-zone conntrack
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
