ice: Support to separate GTP-U uplink and downlink
To apply different input set for GTP-U packet with or without extend
header as well as GTP-U uplink and downlink, we need to add 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.
