From 9a6ad1ad71fbc5a52617e016a3608d71b91f62e8 Mon Sep 17 00:00:00 2001 From: Raed Salem Date: Mon, 18 Nov 2019 14:30:20 +0200 Subject: [PATCH] net/mlx5: Accel, Add core IPsec support for the Connect-X family 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.
