====================
act_ct: Software offload of conntrack_in
This series adds software offload of connections with an established
ct state using the NF flow table offload infrastructure, so
once such flows are offloaded, they will not pass through conntrack
again, and instead act_ct will restore the conntrack info metadata
on the skb to the state it had on the offload event - established.
Act_ct maintains an FT instance per ct zone. Flow table entries
are created, per ct connection, when connections enter an established
state and deleted otherwise. Once an entry is created, the FT assumes
ownership of the entry, and manages it's aging.
On the datapath, first lookup the skb in the zone's FT before going
into conntrack, and if a matching flow is found, restore the conntrack
info metadata on the skb, and skip calling conntrack.
Note that this patchset is part of the connection tracking offload feature.
Hardware offload of connections with an established ct state series will follow
this one.

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.
