From 11d80f79dd9f871a52feba4bf24b5ac39f448eb7 Mon Sep 17 00:00:00 2001 From: Jie Wang Date: Thu, 7 Mar 2024 09:01:14 +0800 Subject: [PATCH] net: hns3: fix port duplex configure error in IMP reset Currently, the mac port is fixed to configured as full dplex mode in hclge_mac_init() when driver initialization or reset restore. Users may change the mode to half duplex with ethtool, so it may cause the user configuration dropped after reset. To fix it, don't change the duplex mode when resetting.
