The Classifier flow table has 512 entries, that contains lookups commands executed consecutively for every flow. Since we have 21 different flows, we have to carefully manage the flow table use. As of today, the start index of a lookup sequence is computed directly based in the flow->id. There are 8 reserved flow ids, from 0-7, which don't have any corresponding sequence in the flow table. We can therefore ignore them when computing the index, and make so that the first non-reserved flow point to the very beginning of the flow table.

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.
