By default, uadk only alloc two queues for each algorithm, which will impact performance. Set queue pair number as required in dev_configure. The default max queue pair number is 8, which can be modified via para: max_nb_queue_pairs

Example: sudo dpdk-test-crypto-perf -l 0-10 --vdev crypto_uadk,max_nb_queue_pairs=10 -- --devtype crypto_uadk --optype cipher-only --buffer-sz 8192
