[v4,04/14] crypto/mlx5: add basic operations
Checks
Commit Message
From: Shiri Kuzin <shirik@nvidia.com>
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 support of get info function:
-mlx5_crypto_dev_infos_get- function used to get specific
information of a device.
Added config struct to user private data with the fields socket id,
number of queue pairs and feature flags to be disabled.
Signed-off-by: Shiri Kuzin <shirik@nvidia.com>
Acked-by: Matan Azrad <matan@nvidia.com>
