SMFS dr matchers are processed sequentially in hardware according to their priorities, and not skipped if empty. Currently, smfs ct fs creates four predefined dr matchers per ct table (ct/ct nat) with hardcoded priority. Compared to dmfs ct fs using autogroups, this might cause additional hops in fastpath for traffic patterns that match later priorties, even if previous priorites are empty, e.g user only using ipv6 UDP traffic will have additional 3 hops. Create the matchers dynamically, using the highest priority available, on first rule usage, and remove them on last usage.

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.
