Currently, if a user wants to run pmtu.sh and cover all the provided test cases, they need to install the Open vSwitch userspace utilities. This dependency is difficult for users as well as CI environments, because the userspace build and setup may require lots of support and devel packages to be installed, system setup to be correct, and things like permissions and selinux policies to be properly configured.
The kernel selftest suite includes an ovs-dpctl.py utility which can interact with the openvswitch module directly. This lets developers and CI environments run without needing too many extra dependencies - just the pyroute2 python package.
This series enhances the ovs-dpctl utility to provide support for set() and tunnel() flow specifiers, better ipv6 handling support, and the ability to add tunnel vports, and LWT interfaces. Finally, it modifies the pmtu.sh script to call the ovs-dpctl.py utility rather than the typical OVS userspace utilities.
NOTE: This could also be applied as-is. I'm trying to get the vng test working in my environment, so I submitted as RFC because I didn't get to test with the config change in 7/7.
