Recent FW modifications allow the offloading of non repr ports. These ports exist internally on the NFP. So if a rule outputs to an 'internal' port, then the packet will recirculate back into the system but will now have this internal port as it's incoming port. These ports are indicated by a specific type field combined with an 8 bit port id. Add private app data to assign additional port ids for use in offloads. Provide functions to lookup or create new ids when a rule attempts to match on an internal netdev - the only internal netdevs currently supported are of type openvswitch. Have a netdev notifier to release port ids on netdev unregister. OvS offloads rules that match on internal ports as TC egress filters. Ensure that such rules are accepted by the driver.

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.
