VPP-279: Document changes for vnet/vnet/devices
Add doxygen documentation for dpdk CLI commands. Outside of adding documentation to the CLI Commands, modified the CLI code as follows: * The "set dpdk interface placement" command allows the user to move interface/queues to a different thread. But there is only a subset of threads that are valid. Updated the "show dpdk interface placement" command to display all valid threads, even if all interface/queues have been moved off. Updated the "show dpdk interface hqos placement" the same way. * There is a command to modify the Subport attributes, but no way to display the changes. Added a "Subport" section to the "show dpdk interface hqos" command. * Reworked the "set dpdk interface hqos subport" command. - The current implementation had a local rte_sched_subport_params structure and initialized it to default values, then overwrote with what was input. The side effect of this is that if all the current data is non-default, and a new command is entered with just one attribute, all the remaining attrbutes are getting set back to default under the cover. Very confusing for the user. Updated the code to read the current value and overwrite what has changed. - DPDK does not have a read subport data, so no way query the current applied values. The set command was not updating the local copy that is created at init. Modified the code to store the updated values if the DPDK apply function was successful. - Several functions repeated the same code to get a pointer to the local HQoS data. Added a utility function.get_hqos(..), to perform this action. Did not port other code to use new function. * The "set dpdk interface hqos pktfield" allows the user to set the packet fields required for classifiying the incoming packet. The classification is across three fields (subport, pipe, tc). The command was using 0,1,2 to represent these three fields, but had no explanation regarding these magic numbers. Updated the command to take the three tokens (subport, pipe, tc) for more clarity. For legacy sake, still allow 0,1,2 to be entered. Also updated the "show dpdk interface hqos" command to show these tokens. * The "set dpdk interface hqos tctbl" maps an interface and value 0-63 to a traffic class and queue. The "show dpdk interface hqos" command showed the internal DPDK magic number for traffic class and queue. Updated the show command to display what was input instead of the magic number. * The "show dpdk hqos queue" command always returns zeros by default because RTE_SCHED_COLLECT_STATS is not defined in DPDK. Took me a while to figure out why I wasn't getting values returned. So returned an error message if RTE_SCHED_COLLECT_STATS is not defined instead of zeros.

+ * This command is used to set the packet fields required for classifiying the
+ * incoming packet. As a result of classification process, packet field
+ * information will be mapped to 5 tuples (subport, pipe, traffic class, pipe,
+ * color) and stored in packet mbuf.
+ *
+ * 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
