Thanks Liu for the pointer to function implemented in testpmd.c

Just want to know in RX configured pools, what scheduling method is used in polling the  queues.

Yes, if you hope TX is configured DCB mode, and 128 TX queues are needed. In testpmd codes, there is an example how to use 128 RX queue and 128 TX queue simultaneously in vmdq+dcb mode.
The example function is get_eth_dcb_conf() in testpmd.c file.

Hi team,

As per dpdk programming guide on VMDq+DCB will configure each Ethernet port to 16 pools with 8 queues each. 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.
