Hi,

this information is not preserved in the DPDK mbuf structure, so is lost
after the call to rx-burst. The DPDK port field stores the port number on
return from rx_burst, but your app could look to reuse this field to store
the queue number also. For example, if you have only a few input ports, you
could encode the port number in the high bits of the "port" field, and
store the rx queue in the lower bits. This could be done as an rx-callback
if you want to avoid adjusting your app following each and every rx-burst
call.
