In the previous mail, I wrote regarding mpls packet forwarding problem in
ovs. My ovs switch version is 2.3.1. I don't what is linux kernel version
of my ovs and don't know how to check it.
Is that problem needs my linux kernel version to upgrade. If yes, can you
provide me document or something to let me learn how to upgrade linux
kernel version of mininet's ovs switch.
Thanks,
Vishlesh
