As far as I can see ethdev API uses 'port_id' everywhere to
refer to ethdev port by its number. So, I suggest

struct rte_flow_item_ethdev {
    uint16_t port_id; /**< ethdev port ID */
};

Basically I agree with Ori, that just "id" is a bit confusing
even when it is a member of the _ethdev structure, but I'd
prepend "port_"  a field name to sync with ethdev API which
uses port_id. So, we have ethdev->port_id.

Andrew.
