From 05564d0ae075b7a73339eaa05296c3034e439c32 Mon Sep 17 00:00:00 2001 From: Aviad Yehezkel Date: Sun, 18 Feb 2018 15:07:20 +0200 Subject: net/mlx5: Add flow-steering commands for FPGA IPSec implementation In order to add a context to the FPGA, we need to get both the software transform context (which includes the keys, etc) and the source/destination IPs (which are included in the steering rule). Therefore, we register new set of firmware like commands for the FPGA. Each time a rule is added, the steering core infrastructure calls the FPGA command layer. If the rule is intended for the FPGA, it combines the IPs information with the software transformation context and creates the respective hardware transform. Afterwards, it calls the standard steering command layer.
