Cos-map Command

ovs-vsctl set-cos-map <TRUE|FALSE>

From Picos-2.6, user can enable/disable the cos-mapping, the default value is disabled. Once cos-mapping is enabled, the packet with the different cos value is mapped to queue0-7.
Usage:

 ovs-vsctl set-cos-map true
 ovs-vsctl set-cos-map false

Set dscp map on port:
 ovs-vsctl set interface ge-1/1/1 dscp_map=0=q1,1=q1,2=q2    
 equal to:
 ovs-vsctl set interface ge-1/1/1 dscp_map:0=q1 dscp_map:1=q1 dscp_map:2=q2  

 Note:
  dscp range is [0, 63];
  queue range value is {q0, q1, q2, q3, q4, q5, q6, q7};
  if a dscp value is not configured, the default queue is q0.

Clear all dscp map on port:
 ovs-vsctl clear interface ge-1/1/1 dscp_map

 Note:
 if no dscp_map configuration, the default map is:

       dscp   queue
