Subject: [RFC net-next 4/6] selftests: openvswitch: adjust datapath NL message

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 messages where we need to do decode
of datapath information that could include the per-cpu PID
map

Fixes: 25f16c873fb1 ("selftests: add openvswitch selftest suite")
