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).
