Subject: [net-next V2 06/15] net/mlx5: Accel, Add core IPsec support for the Connect-X family
From: Raed Salem <raeds@...lanox.com>
This to set the base for downstream patches to support
the new IPsec implementation of the Connect-X family.
Following modifications made:
- Remove accel layer dependency from MLX5_FPGA_IPSEC.
- Introduce accel_ipsec_ops, each IPsec device will
have to support these ops.
