The upcall socket interface can be exercised now to make sure that
future feature adjustments to the field can maintain backwards
compatibility.

Add a basic set of fields to print in a 'dpflow' format. This will be
used by future commits to check for flow fields after parsing, as
well as verifying the flow fields pushed into the kernel from
userspace.

Includes an associated test to generate netns and connect
interfaces, with the option to include packet tracing.
This will be used in the future when flow support is added
for additional test cases.

The netlink message for creating a new datapath takes an array
of ports for the PID creation. This shouldn't cause much issue
but correct it for future cases where we need to do decode of
datapath information that could include the per-cpu PID map.
Fixes: 25f16c873fb1 ("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.
