Hi team,

When we perform VLAN tagged packet transmission using 
rte_eth_tx_burst(), does the dpdk library will enqueue the packets to 
different CoS queues baseed upon QoS priority ? Provided ports are 
configured in DCB mode.

Similarly while reception rte_eth_rx_burst(), does it poll all the CoS 
queues and dequeue the packets based on priority of queue ?

Finally want to know, what scheduling is employed to dequeue the packets 
from different QoS queues ?

Thanks in advance,
