When classifying a packet pertaining to a given flow, the classifier will issue multiple lookup commands until it finds one with the 'last' bit set. It expects all prorities to be assign continuously (although not necessarily in an ordered fashion) from 0 to the number of lookups. We can initialize this once, and make sure unused lookups are given an empty port map. This avoids having to maintain priorities and the information of which lookup is the last.

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.
