/* The i40evf_ptype_lookup table is used to convert from the 8-bit ptype in the
 * hardware to a bit-field that can be used by SW to more easily determine the
 * packet type.
 *
 * Macros are used to shorten the table lines and make this table human
 * readable.
 *
 * We store the PTYPE in the top byte of the bit field - this is just so that
 * we can check that the table doesn't have a row missing, as the index into
 * the table should be the PTYPE.
 *
 * Typical work flow:
 *
 * IF NOT i40evf_ptype_lookup[ptype].known
 * THEN
 *      Packet is unknown
 * ELSE IF i40evf_ptype_lookup[ptype].outer_ip == I40E_RX_PTYPE_OUTER_IP
 *      Use the rest of the fields to look at the tunnels, inner protocols, etc
 * ELSE
 *      Use the enum i40e_rx_l2_ptype to decode the packet type
 * ENDIF
