Implement a per-queue pool of action STEs that match STEs can link to, regardless of matcher. The code relies on hints to optimize whether a given rule is added to rx-only, tx-only or both. Correspondingly, action STEs need to be added to different RTC for ingress or egress paths. For rx-and-tx rules, the current rule implementation dictates that the offsets for a given rule must be the same in both RTCs. To avoid wasting STEs, each action STE pool element holds 3 pools: rx-only, tx-only, and rx-and-tx, corresponding to the possible values of the pool optimization enum. The implementation then chooses at rule creation / update which of these elements to allocate from. Each element holds multiple action STE tables, which wrap an RTC, an STE range, the logic to buddy-allocate offsets from the range, and an STC that allows match STEs to point to this table. When allocating offsets from an element, we iterate through available action STE tables and, if needed, create a new table. Similar to the previous implementation, this iteration does not free any resources. This is implemented in a subsequent 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 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.
