Subject: [PATCH net-next 11/11] net: hns3: Refine hns3_get_link_ksettings()
Date: Mon, 3 Sep 2018 11:21:56 +0100	[thread overview]
Message-ID: <20180903102156.18676-12-salil.mehta@huawei.com> (raw)
In-Reply-To: <20180903102156.18676-1-salil.mehta@huawei.com>

From: Jian Shen <shenjian15@huawei.com>

In the previous implement, the query operation for fibre port and copper
port are mixed. This patch refines it by seperating them based on the port
type.
