I= n testpmd codes, there is an example how to use 128 RX queue and 128 TX que= ue simultaneously in vmdq+dcb mode. The example function is get_eth_dcb_conf() in testpmd.c file.

Which means per port will have 128 Rx & Tx= queues. The question is, in order to have end 2 end QoS support the port should get= configured with 128 Rx as well as 128 Tx queues ? Note: I am considering same port for Rx & Tx. Thanks, Sunil
