Subject[Patch net-next 04/12] net: hns3: fix port info query issue for copper port
Date
From: Jian Shen <shenjian15@huawei.com>

In original codes, for copper port which doesn't connect to phy,
it always returns -EOPNOTSUPP when query port information. This
patch fixes it by return the port information of MAC.

Fixes: 5f373b158523 ("net: hns3: Fix speed/duplex information loss problem when executing ethtool ethx cmd of VF")
