+CVL configure QoS for vf/vsi in DCF
+===================================
+
+Description
+===========
+
+Support ETS-based QoS configuration, including Arbiters configuration (strict priority, WFQ)
+and BW Allocation and limitation.
+1. Add a new virtchnl capability to indicate support for QoS
+2. Enable DCF to set BW limits (min, max) for DPDK AVFs and arbitration mode.
+   To be accomplished by way of new DCF specific virtchnl op.
+   a) Bandwidth limits per VF (VSI) are within the context of BW allocated for the individual TCs
+   at TC layer (layer 2) in the topology.  The profiles will be added at the VSI level.
+   b) In strict arbitration mode (vs ETS mode) a PIR can be applied to layer 2 TC nodes
+   by the DCF for predictable behavior.
+3. Enable DPDK iAVF to query QoS capability, such as UP to TC mapping,
+   available BW (min, max) per TC etc. To be accomplished by way of new advance virtchnl op.
+4. Enable DPDK iAVF to set TC to queue mapping, to be accomplished by way of new advance virtchnl op.
+
+Note: The AVF inherits TCs that are configured on the PF. DCF tunes the BW allocation per TC for the target AVF.
+
+Prerequisites
+=============
+
+1. Hardware:
+   1 port from columbiaville_100g(NIC-1), 2 ports from columbiaville_25g(NIC-2)
+   one 100G cable, one 10G cable::
+
+    +---------------------------------+
+    |  DUT           |  IXIA          |
+    +=================================+
+    |               100G              |
+    | NIC-1,Port-1  ---  IXIA, Port-1 |
+    |               10G               |
+    | NIC-2,Port-1  ---  NIC-2,Port-2 |
+    +---------------------------------+
+
+   assume that device ID and pci address of NIC-1,Port-1 are ens785f0 and 18:00.0,
+   device ID and pci address of NIC-2,Port-1 are ens802f0 and 86:00.0.
+
+2. software:
+
+   - dpdk: http://dpdk.org/git/dpdk
+   - runtime command: https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html
+   - lldptool: install the tool to configure DCB::
+
+    apt install lldpad
+
+   or::
+
+    yum install lldpad
+
+3. don't allow the peer port modify the DCB parameter::
+
+    lldptool -T -i ens802f0 -V ETS-CFG willing=no
+    lldptool -T -i ens785f0 -V ETS-CFG willing=no
+
+4. Configure DCB TC bandwidth with lldp tool::
+
+    lldptool -T -i enp785s0f0 -V ETS-CFG willing=no tsa=0:strict,1:strict,2:strict,3:strict,4:strict,5:strict,6:strict,7:strict up2tc=0:0,1:0,2:0,3:1,4:2,5:0,6:0,7:0 tcbw=10,30,60,0,0,0,0,0
+
+   or configure DCB with dcbgetset tool(an internal tool to set DCB without peer negotiation)::
+
+    ./dcbgetset enp785s0f0 --ieee --up2tc 0,0,0,1,2,0,0,0 --tcbw 10,30,60,0,0,0,0,0,0 --tsa 0,0,0,0,0,0,0,0 --pfc 0,0,0,0,0,0,0,0
+
+5. Generate 2 VFs on NIC-1,Port-1 and NIC-2,Port-1::
+
+    echo 2 > /sys/bus/pci/devices/0000:18:00.0/sriov_numvfs
+    echo 2 > /sys/bus/pci/devices/0000:86:00.0/sriov_numvfs
+
+6. Set each VF0 as trust and set each VF1 mac address::
+
+    ip link set dev ens785f0 vf 0 trust on
+    ip link set ens785f0 vf 1 mac 00:11:22:33:44:55
+    ip link set dev ens802f0 vf 0 trust on
+    ip link set ens802f0 vf 1 mac 00:11:22:33:44:66
+
+7. Bind VFs to dpdk driver::
+
+    modprobe vfio-pci
+    ./usertools/dpdk-devbind.py -b vfio-pci 0000:18:01.0 0000:18:01.1 0000:86:01.0 0000:86:01.1
+    ./usertools/dpdk-devbind.py -s
+    0000:18:01.0 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+    0000:18:01.1 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+    0000:86:01.0 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+    0000:86:01.1 'Ethernet Adaptive Virtual Function 1889' drv=vfio-pci unused=iavf
+
+8. 100G testpmd setting, just use 100G NIC port, start testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 2-10 -n 4 -a 18:01.0,cap=dcf -a 18:01.1 -- -i --txq=8 --rxq=8 --nb-cores=8 --port-topology=loop
+
+   10G testpmd setting, use 100G NIC and 25G NIC ports, start testpmd::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 2-10 -n 4 -a 18:01.0,cap=dcf -a 18:01.1 -a 86:01.0,cap=dcf -a 86:01.1 -- -i --txq=8 --rxq=8 --nb-cores=8
+
+Test case 1: strict mode, check peak_tb_rate
+============================================
+Note: In strict mode, the "--tcbw" parameter is invalid.
+the throughput is only limited by shaper profile,
+and the TC priority follows the default order.
+this case is to check the max rate of node limited by peak_tb_rate,
+when the scheduler use strict priority mode in different user priority.
+
+1. DCB setting, set 3 TCs bandwidth with strict mode::
+
+    ./dcbgetset ens785f0  --ieee --up2tc 0,0,0,1,2,0,0,0 --tcbw 10,30,60,0,0,0,0,0 --tsa 0,0,0,0,0,0,0,0 --pfc 0,0,0,0,0,0,0,0   
+    ifconfig ens785f0 up
+
+2. start testpmd with 100G setting, then set profile and TC mapping::
+
+    port stop all
+    add port tm node shaper profile 0 1 1000000 0 2000000 0 0 0    
+    add port tm node shaper profile 0 2 1000000 0 4000000 0 0 0    
+    add port tm nonleaf node 0 1000 -1 0 1 0 -1 1 0 0              
+    add port tm nonleaf node 0 900 1000 0 1 1 -1 1 0 0    
+    add port tm nonleaf node 0 800 1000 0 1 1 -1 1 0 0     
+    add port tm nonleaf node 0 700 1000 0 1 1 -1 1 0 0  
+
+    add port tm leaf node 0 0 900 0 1 2 1 0 0xffffffff 0 0        
+    add port tm leaf node 0 1 900 0 1 2 1 0 0xffffffff 0 0        
+    add port tm leaf node 0 2 800 0 1 2 2 0 0xffffffff 0 0       
+    add port tm leaf node 0 3 800 0 1 2 2 0 0xffffffff 0 0
+    add port tm leaf node 0 4 700 0 1 2 2 0 0xffffffff 0 0       
+    add port tm leaf node 0 5 700 0 1 2 2 0 0xffffffff 0 0          
+    port tm hierarchy commit 0 no
+
+    add port tm nonleaf node 1 1000 -1 0 1 0 0 1 0 0
+    add port tm nonleaf node 1 900 1000 0 1 1 0 1 0 0
+    add port tm nonleaf node 1 800 1000 0 1 1 0 1 0 0
+    add port tm nonleaf node 1 700 1000 0 1 1 0 1 0 0
+    add port tm leaf node 1 0 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 1 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 2 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 3 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 4 800 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 5 800 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 6 700 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 7 700 0 1 2 0 0 0xffffffff 0 0
+    port tm hierarchy commit 1 no
+    port start all
+    set fwd mac
+    start
+
+3. since configured 3 TCs, send four streams from IXIA,
+   mac address is vf1's mac address: "00:11:22:33:44:55", vlan=0, user priority=2,5,3,4,
+   user priority 2/5 map to TC0, 3 maps to TC1, 4 maps TC2.
+   frame size is 68 bytes(4 bytes vlan field added to 64 bytes packet), each stream desired 25% max rate.
+   send each stream separately, check the TX throughput of each priority and queue mapping:
+   user priority=2, throughput is 2MBps, mapping to queue0-3;
+   user priority=5, throughput is 2MBps, mapping to queue0-3;
+   user priority=3, throughput is 4MBps, mapping to queue4-5;
+   user priority=4, throughput is 4MBps, mapping to queue6-7;
+   send the four streams synchronously, the sum of throughput is 10MBps.
+   and the queue mapping is correct.
+
+4. restart testpmd, and map all the queues to 2 TCs(TC0 and TC1)::
+
+    port stop all
+    add port tm node shaper profile 0 1 1000000 0 2000000 0 0 0
+    add port tm node shaper profile 0 2 1000000 0 4000000 0 0 0
+    add port tm nonleaf node 0 1000 -1 0 1 0 -1 1 0 0              
+    add port tm nonleaf node 0 900 1000 0 1 1 -1 1 0 0    
+    add port tm nonleaf node 0 800 1000 0 1 1 -1 1 0 0     
+    add port tm nonleaf node 0 700 1000 0 1 1 -1 1 0 0  
+    add port tm leaf node 0 0 900 0 1 2 1 0 0xffffffff 0 0        
+    add port tm leaf node 0 1 900 0 1 2 1 0 0xffffffff 0 0        
+    add port tm leaf node 0 2 800 0 1 2 2 0 0xffffffff 0 0       
+    add port tm leaf node 0 3 800 0 1 2 2 0 0xffffffff 0 0
+    add port tm leaf node 0 4 700 0 1 2 2 0 0xffffffff 0 0       
+    add port tm leaf node 0 5 700 0 1 2 2 0 0xffffffff 0 0          
+    port tm hierarchy commit 0 no
+    add port tm nonleaf node 1 1000 -1 0 1 0 0 1 0 0
+    add port tm nonleaf node 1 900 1000 0 1 1 0 1 0 0
+    add port tm nonleaf node 1 800 1000 0 1 1 0 1 0 0
+    add port tm nonleaf node 1 700 1000 0 1 1 0 1 0 0
+    add port tm leaf node 1 0 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 1 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 2 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 3 900 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 4 800 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 5 800 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 6 800 0 1 2 0 0 0xffffffff 0 0
+    add port tm leaf node 1 7 800 0 1 2 0 0 0xffffffff 0 0
+    port tm hierarchy commit 1 no
+    port start all
+    set fwd mac
+    start
+
+5. send the same four streams as step3.
+   send each stream separately, check the TX throughput of each priority and queue mapping:
+   stream 4 are dropped by vf1.
+   user priority=2, throughput is 2MBps, mapping to queue0-3;
+   user priority=5, throughput is 2MBps, mapping to queue0-3;
+   user priority=3, throughput is 4MBps, mapping to queue4-7;
+   user priority=4, throughput is 0, no mapping queues.
+   send the four streams synchronously, the sum of throughput is 6MBps.
+   and the queue mapping is correct.
+
+Test case 2: ets mode, check peak_tb_rate
+=========================================
+Note: In ETS mode, the "--tcbw" parameter is valid.
+the throughput is only limited by TC bandwidth distribution and shaper profile,
+and the TC priority follows the value of the "--tcbw" setting.
+this case is to check the max rate of node limited by tcbw distribution and peak_tb_rate.
+when the scheduler use ETS mode in different user priority.
+
+1. DCB setting, set 2 TCs bandwidth with ets mode::
+
+    ./dcbgetset ens785f0 --ieee --up2tc 0,0,0,0,1,1,1,1 --tcbw 20,80,0,0,0,0,0,0 --tsa 2,2,2,2,2,2,2,2 --pfc 0,0,0,0,0,0,0,0   
+    ./dcbgetset ens802f0 --ieee --up2tc 0,0,0,0,1,1,1,1 --tcbw 20,80,0,0,0,0,0,0 --tsa 2,2,2,2,2,2,2,2 --pfc 0,0,0,0,0,0,0,0   
+    ifconfig ens785f0 up
+    ifconfig ens802f0 up
+
+2. start testpmd with 10G setting, then set profile and TC mapping::
+
+    set portlist 0,2,1,3
+    show config fwd
+    port stop all
+    add port tm node shaper profile 0 1 10000000 0 4000000000 0 0 0    
+    add port tm nonleaf node 0 1000 -1 0 1 0 -1 1 0 0              
+    add port tm nonleaf node 0 900 1000 0 1 1 -1 1 0 0    
+    add port tm nonleaf node 0 800 1000 0 1 1 -1 1 0 0

+    port tm hierarchy commit 3 yes
+    port start all
+    set fwd mac
+    start
+
+3. send two streams from IXIA, vlan=0, priority=0/4(TC0/TC1),
+   mac address is VF1's mac address "00:11:22:33:44:55",
+   frame size is 68 bytes(4 bytes vlan field added to 64 bytes packet), each stream desired 50% max rate.
+   send each stream separately, check the port3(VF1 of 25G port) stats:
+   both of the tx rate is about 7.3Gbps(linerate);
+   stop forward, check queue mapping:
+   when send stream of UP=0, the tx queues are queue0-queue3;
+   when send stream of UP=4, the tx queues are queue4-queue7;
+   send 2 streams synchronously, each 50%max,
+   check the port3 stats, the tx rate is about 7.3Gbps,
+   stop forward, check the result:
+   the throughput's proportion of queue0-3 and queue4-7 is about 20:80 as the DCB TC bandwidth setting.
+
+4. set both two profiles' PIR to 500000000, other settings are the same as step2, 
+   send same streams as step3.
+   send each stream separately, check the port3 tx rate is about 3.95Gbps, closed to the PIR 4Gbps,
+   check queue mapping is same as step3.
+   Send the two streams synchronously, the throughput is limited by the cable about 7.3Gbps.
+   check the port3 stats, the tx rate is still about 7.3Gbps,
+   stop forward, check the result, queue0-queue3 map TC0, queue4-queue7 map TC1
+   TC0’s rate is about 3.34Gbps, TC1’s rate is about 3.95Gbps.
+   the two stream’s occupation is more than 20:80, about 45:55.
+   because TC1 throughput is limited by PIR, so the rest throughput is occupied by TC0.
+
+Test case 3: strict mode, check cmit_tb_rate
+============================================
+this case is to check the guaranteed rate of node set by cmit_tb_rate.
+
+1. DCB setting, set 2 TCs bandwidth with strict mode::
+

+2. start testpmd with 10G setting, then set profile and TC mapping as test_case 2 step2.
+
+3. send two streams from IXIA,
+   mac address is VF1's mac address "00:11:22:33:44:55", vlan=0, priority=0/3(TC0/TC1),
+   frame size is 68 bytes(4 bytes vlan field added to 64 bytes packet), each stream desired 50% max rate.
+   send each stream separately, check the port3(VF1 of 25G port) tx rate is about 7.3Gbps,
+   check queue mapping is same as test_case 2 step3.
+   send 2 streams synchronously, each 50%max
+   check the port3 stats, the tx rate is about 7.3Gbps,
+   stop forward, check the result,
+   queue0-queue3 which mapping to TC0 should have 80Mbps rate
+   queue4-queue7 which mapping to TC1 have about 7.22Gbps.
+
+Note: the cmit of the profile is not supported now, so the current expected result is:

+4. send 4 streams synchronously, stream0-1's mac address is vf1's, vlan id=0, UP=2/3(TC0/TC1),
+   streams2-3's mac address is vf2's, vlan id=0, UP=2/3(TC0/TC1),
+   frame size 68 bytes, each stream allocates 25%max.
+   check the vf4 and vf5 stats, the sum of tx rate is 7.27Gbps, each vf tx is 3.64Gbps.
+   in each vf, TC0 should occupied 0.8Gbps, the rest of throughput is occupied by TC1, which is about 2.84Gbps
+   stop the fwd, check each queue's tx stats,
+   vf4's queue0-queue3 and vf5's queue0-queue1 map to TC0, which occupied 0.8Gbps,
+   vf4's queue4-queue7 and vf5's queue2-queue7 map to TC1, which occupied 2.84Gbps.
+
+Note: now, the cmit_tb_rate setting can't take work, it is not supported by kernel.
+so the current status should be: all the TX throughput are occupied by TC1, TC0 should have no throughput.
+
+Test case 7: 2 iavf VFs, ets mode
+=================================
+in ETS mode, calculate the sum value of different vf node which binded to same TC,
+the proportion of the value of different TC is consistent to TC bandwitch distribution
+
+1. DCB setting, set 3 TCs bandwidth with ets mode::
+
+    ./dcbgetset ens785f0  --ieee --up2tc 0,0,0,1,2,0,0,0 --tcbw 10,30,60,0,0,0,0,0 --tsa 2,2,2,2,2,2,2,2 --pfc 0,0,0,0,0,0,0,0   
+    ./dcbgetset ens802f0  --ieee --up2tc 0,0,0,1,2,0,0,0 --tcbw 10,30,60,0,0,0,0,0 --tsa 2,2,2,2,2,2,2,2 --pfc 0,0,0,0,0,0,0,0   
+
+2. create 3 VFs on each pf::
+
+    echo 3 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
+    ip link set dev ens785f0 vf 0 trust on
+    ip link set ens785f0 vf 1 mac 00:11:22:33:44:55
+    ip link set ens785f0 vf 2 mac 00:11:22:33:44:66
+    ./usertools/dpdk-devbind.py -b vfio-pci 18:01.0 18:01.1 18:01.2
+    echo 3 > /sys/bus/pci/devices/0000\:86\:00.0/sriov_numvfs
+    ip link set dev ens802f0 vf 0 trust on
+    ip link set ens802f0 vf 1 mac 00:11:22:33:44:77
+    ip link set ens802f0 vf 2 mac 00:11:22:33:44:88

+    ifconfig ens785f0 up
+
+2. start testpmd with 100G setting, add vlan filter,
+   then set profile and TC mapping::
+
+    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 2-10 -n 4 -a 18:01.0,cap=dcf -a 18:01.1 -- -i --txq=8 --rxq=8 --nb-cores=8 --port-topology=loop
