+Test case 20: delete qos setting
+================================
+the case is to check the support to delete QoS settings.
+
+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 leaf node 0 5 700 0 1 2 2 0 0xffffffff 0 0
+
+3. delete the shaper profile and nonleaf node::
+
+    del port tm node 0 1000
+    node id: cannot delete a node which has children (error 33)
+    del port tm node 0 700
+    node id: cannot delete a node which has children (error 33)
+    del port tm node shaper profile 0 1
+    shaper profile null: profile in use (error 10)
+
+   the nodes can't be deleted due to the children nodes.
+   delete the leaf nodes first, then delete the nonleaf nodes and shaper profile::
+
+    del port tm node 0 5
+    del port tm node 0 4
+    del port tm node 0 3
+    del port tm node 0 2
+    del port tm node 0 1
+    del port tm node 0 0
+    del port tm node 0 700
+    del port tm node 0 800
+    del port tm node 0 900
+    del port tm node 0 1000
+    del port tm node shaper profile 0 1
+    del port tm node shaper profile 0 2
+
+   deleted successfully.
+
+4. add the settings again as step2, then commit the configuration::
+
+    port tm hierarchy commit 0 no
+
+   delete the leaf node::
+
+    del port tm node 0 5
+    cause unspecified: already committed (error 1)
+
+   check the node can't be deleted after committed.
+
+5. all the operation has the same result on port 1.
