In rx burst function, rxq object is used in data path. For best data performance, it's shared-rxq object in case of shared rxq enabled.
I think eth api defined rxq object for performance as well, specific on data plane.
Hardware saves port info received packet descriptor for my case.
Can't tell which device's queue with this shared rxq object, control path can't use this shared rxq anymore, have to be specific on dev and queue id.
