Subject: [net-next 03/15] net/mlx5: Add IFC bits and enums for crypto key

From: Saeed Mahameed <[email-masked]>
Date: Mon, 30 Jan 2023 19:11:49 -0800

From: Jianbo Liu <[email-masked]>

Add and extend structure layouts and defines for fast crypto key
update. This is a prerequisite to support bulk creation, key
modification and destruction, software wrapped DEK, and SYNC_CRYPTO
command.
