Hello Greg,

Thanks for your reply !

Followed your instruction and tried to print the Device name but it prints
the Bridge name and Bridge Interface name. I am sharing the two screenshot
one is the Log image and another is the ovs-vsctl show output(*netdev type
is Internal)*, Please give your suggestion.

And I would like you to give you suggestion for the below issue
1. I am planning to extend the queue at egress port of the ovs to 8 queues
but really don't have the exact clue where should i change the code ,
should i explore Linux qdisc like pfifo_fast or something else .



Regards
Rakesh Kumar
