From 16b5e50147c21edef7133f204c43465f0c03c3f5 Mon Sep 17 00:00:00 2001 From: Fuyun Liang Date: Fri, 3 Nov 2017 12:18:25 +0800 Subject: [PATCH] net: hns3: fix for getting autoneg in hns3_get_link_ksettings This patch fixes a bug for ethtool's get_link_ksettings(). When phy exists, we should get autoneg from phy rather than from mac. Because the value of mac.autoneg is invalid when phy exists.
