We tried hard to use the hardware as a storage area, which made things needlessly complex in that we had to both marshall and unmarshall the ethtool_rx_flow_spec into what the CFP hardware understands but it did not require any driver level allocations, so that was nice. Keep a copy of the ethtool_rx_flow_spec rule we want to insert, and also make sure we don't have a duplicate rule already. This greatly speeds up the deletion time since we only need to clear the slice's valid bit and not perform a full read. This is a preparatory step for being able to restore rules upon system resumption where the hardware loses its context partially or entirely.

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.
