+- * 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

+# QoS Hierarchical Scheduler    {#qos_doc}
+
+The Quality-of-Service (QoS) scheduler performs egress-traffic management by
+prioritizing the transmission of the packets of different type services and
+subscribers based on the Service Level Agreements (SLAs). The QoS scheduler can
+be enabled on one or more NIC output interfaces depending upon the
+requirement.
+
+
+## Overview
+
+The QoS scheduler supports a number of scheduling and shaping levels which
+construct hierarchical-tree. The first level in the hierarchy is port (i.e.
+the physical interface) that constitutes the root node of the tree. The
+subsequent level is subport which represents the group of the
+users/subscribers. The individual user/subscriber is represented by the pipe
+at the next level. Each user can have different traffic type based on the
+criteria of specific loss rate, jitter, and latency. These traffic types are
+represented at the traffic-class level in the form of different traffic-
+classes. The last level contains number of queues which are grouped together
+to host the packets of the specific class type traffic.
+
+The QoS scheduler implementation requires flow classification, enqueue  and
+dequeue operations. The flow classification is mandatory stage for HQoS where
+incoming packets are classified by mapping the packet fields information to
+5-tuple (HQoS subport, pipe, traffic class, queue within traffic class, and
+color) and storing that information in mbuf sched field. The enqueue operation
+uses this information to determine the queue for storing the packet, and at
+this stage, if the specific queue is full, QoS drops the packet. The dequeue
+operation consists of scheduling the packet based on its length and available
+credits, and handing over the scheduled packet to the output interface.
+
+For more information on QoS Scheduler, please refer DPDK Programmer's Guide-
+http://dpdk.org/doc/guides/prog_guide/qos_framework.html
+
+
+### QoS Scheduler Parameters
+
+Following illustrates the default HQoS configuration for each 10GbE output
+port:
+
+Single subport (subport 0):
+  - Subport rate set to 100% of port rate
+  - Each of the 4 traffic classes has rate set to 100% of port rate
+
+4K pipes per subport 0 (pipes 0 .. 4095) with identical configuration:
+  - Pipe rate set to 1/4K of port rate
+  - Each of the 4 traffic classes has rate set to 100% of pipe rate
+  - Within each traffic class, the byte-level WRR weights for the 4 queues are set to 1:1:1:1
+

+### DPDK QoS Scheduler Integration in VPP
+
+The Hierarchical Quality-of-Service (HQoS) scheduler object could be seen as
+part of the logical NIC output interface. To enable HQoS on specific output
+interface, vpp startup.conf file has to be configured accordingly. The output
+interface that requires HQoS, should have "hqos" parameter specified in dpdk
+section. Another optional parameter "hqos-thread"  has been defined which can
+be used to associate the output interface with specific hqos thread. In cpu
+section of the config file, "corelist-hqos-threads" is introduced to assign
+logical cpu cores to run the HQoS threads. A HQoS thread can run multiple HQoS
+objects each associated with different output interfaces. All worker threads
+instead of writing packets to NIC TX queue directly, write the packets to a
+software queues. The hqos_threads read the software queues, and enqueue the
+packets to HQoS objects, as well as dequeue packets from HQOS objects and
+write them to NIC output interfaces. The worker threads need to be able to
+send the packets to any output interface, therefore, each HQoS object
+associated with NIC output interface should have software queues equal to
+worker threads count.
+
+Following illustrates the sample startup configuration file with 4x worker
+threads feeding 2x hqos threads that handle each QoS scheduler for 1x output
+interface.
+
+```
+dpdk {
+  socket-mem 16384,16384
+
+  dev 0000:02:00.0 {
+    num-rx-queues 2
+    hqos
+  }
+  dev 0000:06:00.0 {
+    num-rx-queues 2
+    hqos
+  }
+
+  num-mbufs 1000000
+}
+
+cpu {
+  main-core 0
+  corelist-workers  1, 2, 3, 4
+  corelist-hqos-threads  5, 6
+}
+```
+
+
+### QoS scheduler CLI Commands
+
+Each QoS scheduler instance is initialised with default parameters required to
+configure hqos port, subport, pipe and queues. Some of the parameters can be
+re-configured in run-time through CLI commands.
+
+
+#### Configuration
+
+Following commands can be used to configure QoS scheduler parameters.
+
+The command below can be used to set the subport level parameters such as
+token bucket rate (bytes per seconds), token bucket size (bytes), traffic
+class rates (bytes per seconds) and token update period (Milliseconds).
+
+```
+set dpdk interface hqos subport <interface> subport <subport_id> [rate <n>]
+    [bktsize <n>] [tc0 <n>] [tc1 <n>] [tc2 <n>] [tc3 <n>] [period <n>]
+```
+
+For setting the pipe profile, following command can be used.    
+
+```
+set dpdk interface hqos pipe <interface> subport <subport_id> pipe <pipe_id>
+    profile <profile_id>
+```
+
+To assign QoS scheduler instance to the specific thread, following command can
+be used.
+
+```
+set dpdk interface hqos placement <interface> thread <n>
+```
+
+The command below 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,
+color) and stored in packet mbuf.
+
+```
+set dpdk interface hqos pktfield <interface> id subport|pipe|tc offset <n>
+    mask <hex-mask>
+```
+
+The DSCP table entries used for identifying the traffic class and queue can be set using the command below;   
+
+```  
+set dpdk interface hqos tctbl <interface> entry <map_val> tc <tc_id> queue <queue_id>
+```
+
+
+#### Show Command

+
+### QoS Scheduler Binary APIs
+
+This section explains the available binary APIs for configuring QoS scheduler
+parameters in run-time.
+
+The following API can be used to set the pipe profile of a pipe that belongs
+to a given subport:
+
+```
+sw_interface_set_dpdk_hqos_pipe rx <intfc> | sw_if_index <id>
+    subport <subport-id> pipe <pipe-id> profile <profile-id>
+```
+
+The data structures used for set the pipe profile parameter are as follows;
+
+```
+  /** \\brief DPDK interface HQoS pipe profile set request
+    @param client_index - opaque cookie to identify the sender
+    @param context - sender context, to match reply w/ request
+    @param sw_if_index - the interface
+    @param subport - subport ID
+    @param pipe - pipe ID within its subport
+    @param profile - pipe profile ID
+  */
+  define sw_interface_set_dpdk_hqos_pipe {
+    u32 client_index;
+    u32 context;
+    u32 sw_if_index;
+    u32 subport;

+  };
+
+  /** \\brief DPDK interface HQoS pipe profile set reply

+  */
+  define sw_interface_set_dpdk_hqos_pipe_reply {
+    u32 context;
+    i32 retval;
+  };
+```
+
+The following API can be used to set the subport level parameters, for
+example- token bucket rate (bytes per seconds), token bucket size (bytes),
+traffic class rate (bytes per seconds) and tokens update period.
+
+```
+sw_interface_set_dpdk_hqos_subport rx <intfc> | sw_if_index <id>
+    subport <subport-id> [rate <n>] [bktsize <n>]
+    [tc0 <n>] [tc1 <n>] [tc2 <n>] [tc3 <n>] [period <n>]
+```
+
+The data structures used for set the subport level parameter are as follows;
+
+```
+  /** \\brief DPDK interface HQoS subport parameters set request
+    @param client_index - opaque cookie to identify the sender
