This patch is the first part of update flow implementation. Update flow should support rules with single STE (match STE only), as well as rules with multiple STEs (match STE plus action STEs). Supporting the rules with single STE is straightforward: we just overwrite the STE, which is an atomic operation. Supporting the rules with action STEs is a more complicated case. The existing implementation uses two action RTCs per matcher and alternates between the two for each update request. This implementation was unnecessarily complex and lead to some unhandled edge cases, so the support for rule update with multiple STEs wasn't really functional. This patch removes this code, and the next patch adds implementation of a different approach. Note that after applying this patch and before applying the next patch we still have support for update rule with single STE (only match STE w/o action STEs), but update will fail for rules with action STEs.

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 reStructuredText 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.
