Could you please send the complete patchset for the PMD?
Or is it postponed for 21.08?

We are doing an effort to send it before 21.05-RC1 but remember that we can close it until RC2 (new PMD).

[dpdk-dev] [RFC] drivers: introduce mlx5 crypto PMD

[Matan Azrad]

From: Shiri Kuzin <shirik@nvidia.com>

Add a new PMD for Mellanox devices- crypto PMD.

The crypto PMD will be supported starting Mellanox ConnectX6 and
BlueField2.

The crypto PMD will add the support of encryption and decryption using
the AES-XTS symmetric algorithm.

The crypto PMD requires rdma-core and uses mlx5 DevX.

This patch adds the PCI probing, basic functions, build files and
log utility.
