hello everyone,
i have a doubt here when i am trying the mqprio qdisc of linux on my
physical interface its working but when i am trying on interfaces created
by ovs then mqprio qdisc is not working.

eg:

root at IN:/sys/devices/virtual/net/s1-eth1/queues# sudo tc -g class show dev
ens160
+--(:4) mq
+--(:3) mq
+--(:2) mq
+--(:1) mq

root at IN:/sys/devices/virtual/net/s1-eth1/queues# sudo tc qdisc replace dev
s1-eth1 handle 100: parent root mqprio num_tc 3 map 2 2 1 0 2 2 2 2 2 2 2 2
2 2 2 2 queues 1 at 0 1 at 1 2 at 2 hw 0
