SW steering is able to match only on the exact values of the packet fields, as requested by the user: the user provides mask for the fields that are of interest, and the exact values to be matched on when the traffic is handled. Match Definer is a general FW object that defines which fields in the packet will be referenced by the mask and tag of each STE. Match definer ID is part of STE fields, and it defines how the HW needs to interpret the STE's mask/tag values. Till now SW steering used the definers that were managed by FW and implemented the STE layout as described by the HW spec. Now that we're adding a new type of STE, SW steering needs to define for the HW how it should interpret this new STE's layout. This is done with a programmable match definer. The programmable definer allows to selects which fields will be included in the definer, and their layout: it has up to 9 DW selectors 8 Byte selectors. Each selector indicates a DW/Byte worth of fields out of the table that is defined by HW spec by referencing the offset of the required DW/Byte. This patch adds dr_cmd function to create and destroy MATCH_DEFINER general object.

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.
