Hi,

What is the maximum number of queue pairs in C626 QAT card?

From rte_cryptodev_info_get(), it seems that the maximum number is 2. Is this correct?

Can it be increased via configuration or is this set in hardware?

I have a DPDK application running 5 instances on 5 CPUs. I need the QAT VF to be bound to each of the CPUs. But, this limitation of 2 queue pairs means that only 2 of the CPUs can communicate with QAT VF at any given point. 

Regards,
Venkatesh
