Pre-tunnel rules must direct packets to an internal port based on L2 information. Rules that egress to an internal port are already indicated by a non-NULL device in its nfp_fl_payload struct. Verfiy the rest of the match fields indicate that the rule is a pre-tunnel rule. This requires a full match on the destination MAC address, an option VLAN field, and no specific matches on other lower layer fields (with the exception of L4 proto and flags). If a rule is identified as a pre-tunnel rule then mark it for offload to the pre-tunnel table. Similarly, remove it from the pre-tunnel table on rule deletion. The actual offloading of these commands is left to a following patch.

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.
