From: Shiri Kuzin <shi...@nvidia.com>
The basic dev control operations are configure, close, start, stop and
get info.
Extended the existing support of configure and close:
-mlx5_crypto_dev_configure- function used to configure device.
-mlx5_crypto_dev_close- function used to close a configured
device.
-mlx5_crypto_dev_stop- function used to stop device.
-mlx5_crypto_dev_start- function used to start device.
-mlx5_crypto_dev_infos_get- function used to get info.
Added config struct to user private data with the fields socket id,
number of queue pairs and feature flags to be disabled.
Add the dev_start function that is used to start a configured device.
Add the dev_stop function that is used to stop a configured device.
