[RFC,net-next,0/7] selftests: net: Switch pmtu.sh to use the internal ovs script.

Message

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.

Aaron Conole (6):
  selftests: openvswitch: Support explicit tunnel port creation.
  selftests: openvswitch: Refactor actions parsing.
  selftests: openvswitch: Add set() and set_masked() support.
  selftests: openvswitch: Add support for tunnel() key.
  selftests: openvswitch: Support implicit ipv6 arguments.
  selftests: net: Use the provided dpctl rather than the vswitchd for
    tests.
  selftests: net: add config for openvswitch
