[v2,1/2] ethdev: announce flow API action PORT_ID changes
Checks
Commit Message
By its very name, action PORT_ID means that packets hit an ethdev with the
given DPDK port ID. At least the current comments don't state the opposite.
However some drivers implement it in a different way and direct traffic to
the opposite end of the "wire" plugged to the given ethdev. For example in
the case of a VF representor traffic is redirected to the corresponding VF
itself rather than to the representor ethdev and OvS uses PORT_ID action
this way.
The documentation must be clarified and, likely, rte_flow_action_port_id
structure should be extended to support both meanings.
