From b343b6eefd9d281d1adffe701407c59a4f74b1f9 Mon Sep 17 00:00:00 2001 From: Junyu Jiang Date: Tue, 1 Sep 2020 08:14:36 +0000 Subject: [PATCH] net/iavf: fix mismatch command The "command mismatch" warning shouldn't be triggered by VIRTCHNL_OP_EVENT opcode, because the VIRTCHNL_OP_EVENT opcode is used by PF notifies status change events to VF. This patch fixed the issue.
