Relation between DPDK queue and descriptors

[Mikael R Carlsson]

Hi experts!

I have a hard time to finds a good documentation about the relation between DPDK TX queue and descriptors.

Queue as in rte_eth_tx_queue_setup
Descriptor as in rte_eth_dev_adjust_nb_rx_rx_desc

We suspect we run out of descriptors in TX path, we are not sure here. We use more than one TX queue. Will we get more descriptors if we only use one single TX queue? Does anyone know if there is some good documentation regarding the TX queue and the descriptors?
