From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lipeng Subject: [PATCH net-next 1/6] net: hns3: fix for getting autoneg in hns3_get_link_ksettings Date: Fri, 3 Nov 2017 12:18:25 +0800 Message-ID: <1509682710-94908-2-git-send-email-lipeng321@huawei.com> References: <1509682710-94908-1-git-send-email-lipeng321@huawei.com> Mime-Version: 1.0 Content-Type: text/plain Cc: , , , , To: Return-path: In-Reply-To: <1509682710-94908-1-git-send-email-lipeng321@huawei.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org From: Fuyun Liang 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.
