[dpdk-users] QAT cryto PMD queue pair and Ring Libary

[Changchun Zhang]

Thanks.
The related question, for Ethernet device, if it has been bound to igb_uio driver, who is going to actually implement the rx_ring and tx_ring for the Ethernet PMD? The igb_uio driver?

Changchun (Alex)

[Fiona] This doesn't use the DPDK ring library. They are QAT-specific, hw-supported tx and rx rings.
