The arguments for RX n-tuple traffic direction are filled into structure fields of varying size, some of which are in big-endian rather than native byte order. Currently parse_generic_cmdline() only supports 32-bit integers in native byte order, so this does not work correctly. Replace CMDL_INT and CMDL_UINT with the more explicit CMDL_S32 and CMDL_U32. Add CMDL_U16 and CMDL_U64 for narrower and wider integers, and CMDL_BE16 and CMDL_BE32 for big-endian unsigned integers. Use them for RX n-tuple argument parsing.
