Aaron Conole says:

====================
selftests: openvswitch: Address some flakes in the CI environment

These patches aim to make using the openvswitch testsuite more reliable.
These should address the major sources of flakiness in the openvswitch
test suite allowing the CI infrastructure to exercise the openvswitch
module for patch series.  There should be no change for users who simply
run the tests (except that patch 3/3 does make some of the debugging a bit
easier by making some output more verbose).
