From 4bdba39b703acbe5d0094675a71f736d386fbe96 Mon Sep 17 00:00:00 2001 From: Yevgeny Kliteynik Date: Thu, 19 Nov 2020 04:53:53 +0200 Subject: [PATCH] net/mlx5: DR, Add infrastructure for supporting several steering formats Add a struct of device specific callbacks for STE layer below dr_ste. Each device will implement its HW-specific function, and a comon logic from the DR code will access these functions through the new ste_ctx API. More callbacks will follow in the subsequent patches.
