Subject: [net-next 03/15] net/mlx5: Add IFC bits and enums for crypto key
From: Jianbo Liu <jianbol@...dia.com>
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.
