76035fd12c selftests: openvswitch: Skip drop testing on older kernels
Kernels that don't have support for openvswitch drop reasons also
won't have the drop counter reasons, so we should skip the test
completely.  It previously wasn't possible to build a test case
for this without polluting the datapath, so we introduce a mechanism
to clear all the flows from a datapath allowing us to test for
explicit drop actions, and then clear the flows to build the
original test case.

92e37f20f2 selftests: openvswitch: Add version check for pyroute2
Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite.  Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.

The alternative that Paolo proposed was to only skip when the
add-flow is being run.  This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing).  In that case, it could also be
broken and we would need additional skip logic anyway.  Just draw
a line in the sand now.

4242029164 selftests: openvswitch: add explicit drop testcase
Test explicit drops generate the right drop reason. Also, verify that
the kernel rejects flows with actions following an explicit drop.

2893ba9c1d selftests: openvswitch: add basic ct test case parsing
Forwarding via ct() action is an important use case for openvswitch, but
generally would require using a full ovs-vswitchd to get working. Add a
ct action parser for basic ct test case.

918423fda9 selftests: openvswitch: add an initial flow programming case
The openvswitch self-tests can test much of the control side of
the module (ie: what a vswitchd implementation would process),
but the actual packet forwarding cases aren't supported, making
the testing of limited value.

Add some flow parsing and an initial ARP based test case using
arping utility.  This lets us display flows, add some basic
output flows with simple matches, and test against a known good
forwarding case.

25f16c873f selftests: add openvswitch selftest suite
Previous commit resolves a WARN splat that can be difficult to reproduce,
but with the ovs-dpctl.py utility, it can be trivial.  Introduce a test
case which creates a DP, and then downgrades the feature set.  This will
include a utility 'ovs-dpctl.py' that can be extended to do additional
tests and diagnostics.
