From bcc7a98f0d3cbb18ca2502c278812867f81add48 Mon Sep 17 00:00:00 2001 From: Jie Wang Date: Tue, 19 Apr 2022 11:27:04 +0800 Subject: net: hns3: add failure logs in hclge_set_vport_mtu Currently, There is a low probability that pf mtu configuration fails, but the information in logs is insufficient for problem locating when the VF mtu value is illegally modified. So record the vf index and vf mtu value at the failure scenario. Signed-off-by: Jie Wang Signed-off-by: Guangbin Huang Signed-off-by: David S.
