From 7891de8d8ff500fe04b1e5a6178e8bacc4605831 Mon Sep 17 00:00:00 2001 From: Venkat Duvvuru Date: Sun, 30 May 2021 14:29:13 +0530 Subject: [PATCH] net/bnxt: support GRE flows This patch does the following to support GRE flows: 1. RTE_FLOW_ITEM_TYPE_ANY & RTE_FLOW_ITEM_TYPE_GRE processing 2. Calculate the absolute function ID from the logical VF ID passed as part of RTE_FLOW_ACTION_TYPE_VF action. 3.
