Subject: [PATCH net-next 0/3] selftests: openvswitch: add support for testing upcall interface

The existing selftest suite for openvswitch will work for regression
testing the datapath feature bits, but won't test things like adding
interfaces, or the upcall interface.  Here, we add some additional
test facilities.

First, extend the ovs-dpctl.py python module to support the OVS_FLOW
and OVS_PACKET netlink families, with some associated messages.  These
can be extended over time, but the initial support is for more well
known cases (output, userspace, and CT).

Next, extend the test suite to test upcalls by adding a datapath,
monitoring the upcall socket associated with the datapath, and then
dumping any upcalls that are received.  Compare with expected ARP
upcall via arping.
