Previous patch in series that implements stack devices RX path implements indirect table rules that match on tunnel VNI. After such rule is created all tunnel traffic is recirculated to root table. However, recirculated packet might not match on any rules installed in the table (for example, when IP traffic follows ARP traffic). In that case packets appear on representor of tunnel endpoint VF instead being redirected to the VF itself. Extend slow table with additional flow group that matches on reg_c0 (source port value set by indirect tables implemented by previous patch in series) and reg_c1 (special 0xFFF mark). When creating offloads fdb tables, install one rule per VF vport to match on recirculated miss packets and redirect them to appropriate VF vport. Modify indirect tables code to also rewrite reg_c1 with special 0xFFF mark. Implementation reuses reg_c1 tunnel id bits. This is safe to do because recirculated packets are always matched before decapsulation.

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.
