We will be adding some private VCAP filters that should not interfere in any way with the filters added using tc-flower. So we need to allocate some IDs which will not be used by tc. Currently ocelot uses an u32 id derived from the flow cookie, which in itself is an unsigned long. This is a problem in itself, since on 64 bit systems, sizeof(unsigned long)=8, so the driver is already truncating these. Create a struct ocelot_vcap_id which contains the full unsigned long cookie from tc, as well as a boolean that is supposed to namespace the filters added by tc with the ones that aren't.

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.
