Add code to parse the user-def field into a data structure format. This code is intended to allow future extensions of the user-def field by keeping all code that actually reads and writes the field into a single location. This ensures that we do not litter the driver with references to the user-def field and minimizes the amount of bitwise operations we need to do on the data. Add code which parses the lower 32bits into a flexible word and its offset. This will be used in a future patch to enable flexible filters which can match on some arbitrary data in the packet payload. For now, we just return -EOPNOTSUPP when this is used. Add code to fill in the user-def field when reporting the filter back, even though we don't actually implement any user-def fields yet. Additionally, ensure that we mask the extended FLOW_EXT bit from the flow_type now that we will be accepting filters which have the FLOW_EXT bit set (and thus make use of the user-def field).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
