[dpdk-dev] [PATCH] net/memif: add multiple memif data transmission support

When Multiple slave/master Memif interfaces are created in single
process data transmission over second connection is not successful.

Issue is because of "mq->in_port" is not initialized with
"dev->data->port_id" in memif_msg_enq_add_ring() and
memif_msg_receive_add_ring() functions, and while transmitting packets
over second connection in eth_memif_tx function it refer "mq->in_port"
which is always zero, and leads to data transmission always in 0th port.

To mitigate the issue,"mq->in_port" is initialized with
"dev->data->port_id" in memif_msg_enq_add_ring() and
memif_msg_receive_add_ring() functions.
