Added the GTP QFI field to the Flow director interface to allow matching against this field. Since this field only appears in GTP packets with extension headers, this also requires adding profile TCAM mask matching capability. This allows comprehending different PTYPE attributes by examining flags from the parser. Using this method, different profiles can be used by examining flag values from the parser.
