From: Matan Azrad Date: Tue, 18 Feb 2020 14:45:20 +0000 (+0000) Subject: net/mlx5: fix flow match on GRE key X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=38ad946892830c9fb5f8fe221bf677ee8e9bc819;p=dpdk.git net/mlx5: fix flow match on GRE key The RTE_FLOW_ITEM_TYPE_GRE_KEY means that GRE key should be present on the flow and in addition can explicitly match on the GRE key field itself. When no value is set in this item any GRE key should match the flow. The match on GRE key wrongly was not added if the item fields are NULL while at least the GRE key should be present in the flow. Add the GRE key present match when RTE_FLOW_ITEM_TYPE_GRE_KEY is in the flow item list.
