Each flow is given a context ID that the fw uses (along with its cookie) to identity the flow. The flows stats are updated by the fw via this ID which is a reference to a pre-allocated array entry. In preparation for flow merge code, enable the nfp_fl_payload structure to be accessed via this stats context ID. Rather than increasing the memory requirements of the pre-allocated array, add a new rhashtable to associate each active stats context ID with its rule payload. While adding new code to the compile metadata functions, slightly restructure the existing function to allow for cleaner, easier to read error handling.

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.
