[v2] crypto/uadk: set queue pair in dev_configure
Checks
Commit Message
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

+Initialization
+--------------
+
+To use the PMD in an application, user must:
+
+* Call rte_vdev_init("crypto_uadk") within the application.
+
+* Use --vdev="crypto_uadk" in the EAL options, which will call rte_vdev_init() internally.
+
+The following parameters (all optional) can be provided in the previous two calls:
+
+* max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
+ The max value of max_nb_queue_pairs can be queried from the device property available_instances.
+ Property available_instances value may differ from the devices and platforms.
+ Allocating queue pairs bigger than available_instances will fail.
+
+Example:
+
+.. code-block:: console
+
+ cat /sys/class/uacce/hisi_sec2-2/available_instances
+ 256
+
+ 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
