From d13f9760866884d81563624fbf160f3054b70f19 Mon Sep 17 00:00:00 2001 From: Raslan Darawsheh Date: Thu, 16 Jul 2020 15:14:55 +0300 Subject: [PATCH] net/mlx5: fix flow items size calculation flow_dv_get_item_len returns the actual header size of an rte_flow item. Changing any of the structs for rte_flow items by adding or removing some extra fields will break this function. This fixes the behavior by returning the actual header size of each item.
