The Intel i225 NIC has the possibility to add flex filters which can match up to the first 128 byte of a packet. These filters are useful for all kind of packet matching. One particular use case is Profinet, as the different traffic classes are distinguished by the frame id range which cannot be matched by any other means. Add code to configure and enable flex filters.

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.
