Errors-To: dev-bounces@dpdk.org
Sender: "dev" <dev-bounces@dpdk.org>
The basic dev control operations are configure, close 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.
Added config struct to user private data with the fields socket id,
number of queue pairs and feature flags to be disabled.
