Paul Blakey 41f2c7c342 net/sched: act_ct: Fix promotion of offloaded unreplied tuple
Currently UNREPLIED and UNASSURED connections are added to the nf flow
table. This causes the following connection packets to be processed
by the flow table which then skips conntrack_in(), and thus such the
connections will remain UNREPLIED and UNASSURED even if reply traffic
is then seen. Even still, the unoffloaded reply packets are the ones
triggering hardware update from new to established state, and if
there aren't any to triger an update and/or previous update was
missed, hardware can get out of sync with sw and still mark
packets as new.

Fix the above by:
1) Not skipping conntrack_in() for UNASSURED packets, but still
   refresh for hardware, as before the cited patch.
2) Try and force a refresh by reply-direction packets that update
   the hardware rules from new to established state.
3) Remove any bidirectional flows that didn't failed to update in
   hardware for re-insertion as bidrectional once any new packet
   arrives.

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.
