Subject: net: hns3: fix port info query issue for copper port
Patch-mainline: v5.1-rc1
Git-commit: f18635d52c23594259da2f741399abc6c6f41f15
References: bsc#1126390

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")
