and steering between endpoints using outdated action PORT_ID.
Revisit these examples to make use of new port-based actions.

Mirroring rule with port representors (with "transfer" attribute), the matched

mirrored the packets and sent to port id 2.
Match packets coming from a VM which is referred to by means of
its representor ethdev (port 1), mirror 50% of them to the
said representor (for bookkeeping) as well as encapsulate
all the packets and steer them to the physical port:
