Subject: [PATCH V2 net-next 01/12] net: hns3: check 1000M half for hns3_ethtool_ops.set_link_ksettings
Date: Thu, 4 Apr 2019 16:17:48 +0800	[thread overview]
Message-ID: <1554365879-7932-2-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1554365879-7932-1-git-send-email-tanhuazhong@huawei.com>

From: Peng Li <lipeng321@huawei.com>

Hip08 SOC does not support 1000M half, this patch adds 1000M half
check for hns3_ethtool_ops.set_link_ksettings, so the user can not
set 1000M half by ethtool.
