+- * This command is used to set the packet fields required for classifying the
+- * incoming packet. As a result of classification process, packet field
+- * information will be mapped to 5 tuples (subport, pipe, traffic class, pipe,

+- *
+- * This command has the following parameters:
+- *
+- * - <b><interface></b> - Used to specify the output interface.
+- *
+- * - <b>id subport|pipe|tc</b> - Classification occurs across three fields.
+- * This parameter indicates which of the three masks are being configured. Legacy
+- * code used 0-2 to represent these three fields, so 0-2 is still accepted.
+- *   - <b>subport|0</b> - Currently only one subport is supported, so only
+- * an empty mask is supported for the subport classification.
+- *   - <b>pipe|1</b> - Currently, 4096 pipes per subport are supported, so a
+- * 12-bit mask should be configure to map to the 0-4095 pipes.
+- *   - <b>tc|2</b> - The translation table (see '<em>set dpdk interface hqos
+- * tctbl</em>' command) maps each value (0-63) into one of the 4 traffic classes
+- * per pipe. A 6-bit mask should be configure to map this field to a traffic class.
+- *
+- * - <b>offset <n></b> - Offset in the packet to apply the 64-bit mask for classification.
+- * The offset should be on an 8-byte boundary (0,8,16,24..).
+- *
+- * - <b>mask <hex-mask></b> - 64-bit mask to apply to packet at the given '<em>offset</em>'.
+- * Bits must be contiguous and should not include '<em>0x</em>'.
+- *
+- * The default values for the '<em>pktfield</em>' assumes Ethernet/IPv4/UDP packets with
+- * no VLAN. Adjust based on expected packet format and desired classification field.
+- * - '<em>subport</em>' is always empty (offset 0 mask 0000000000000000)
+- * - By default, '<em>pipe</em>' maps to the UDP payload bits 12 .. 23 (offset 40
+- * mask 0000000fff000000)
+- * - By default, '<em>tc</em>' maps to the DSCP field in IP header (offset 48 mask

- *
- * - <b>id subport|pipe|tc</b> - Classification occurs across three fields.
- * This parameter indicates which of the three masks are being configured. Legacy
- * code used 0-2 to represent these three fields, so 0-2 is still accepted.
- *   - <b>subport|0</b> - Currently only one subport is supported, so only
- * an empty mask is supported for the subport classification.
- *   - <b>pipe|1</b> - Currently, 4096 pipes per subport are supported, so a
- * 12-bit mask should be configure to map to the 0-4095 pipes.
- *   - <b>tc|2</b> - The translation table (see '<em>set dpdk interface hqos
- * tctbl</em>' command) maps each value (0-63) into one of the 4 traffic classes
- * per pipe. A 6-bit mask should be configure to map this field to a traffic class.
- *
- * - <b>offset <n></b> - Offset in the packet to apply the 64-bit mask for classification.
- * The offset should be on an 8-byte boundary (0,8,16,24..).
- *
- * - <b>mask <hex-mask></b> - 64-bit mask to apply to packet at the given '<em>offset</em>'.
- * Bits must be contiguous and should not include '<em>0x</em>'.
- *
- * The default values for the '<em>pktfield</em>' assumes Ethernet/IPv4/UDP packets with
- * no VLAN. Adjust based on expected packet format and desired classification field.
- * - '<em>subport</em>' is always empty (offset 0 mask 0000000000000000)
- * - By default, '<em>pipe</em>' maps to the UDP payload bits 12 .. 23 (offset 40
- * mask 0000000fff000000)
- * - By default, '<em>tc</em>' maps to the DSCP field in IP header (offset 48 mask
- * 00000000000000fc)
- *
- * @cliexpar
- * Example of how modify the '<em>pipe</em>' classification filter to match VLAN:
- * @cliexcmd{set dpdk interface hqos pktfield GigabitEthernet0/8/0 id pipe offset 8 mask 0000000000000FFF}
