This commit introduces support for the "Drop" action in classification offload. This corresponds to the "-1" action with ethtool -N. This is achieved using the color marking actions available in the C2 engine, which associate a color to a packet. These colors can be either Green, Yellow or Red, Red meaning that the packet should be dropped. Green and Yellow colors are interpreted by the Policer, which isn't supported yet. This method of dropping using the Classifier is different than the already existing early-drop features, such as VLAN filtering and MAC UC/MC filtering, which are performed during the Parsing step, and therefore take precedence over classification actions.

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.
