Subject: net: hns3: fix a bug for phy supported feature initialization
Patch-mainline: v4.15-rc1
Git-commit: 439adf885e6dd3b2a64941a167b4c18d3728c6dc
References: bsc#1104353 FATE#326415
This patch fixes a bug for phy supported feature initialization.
Currently, the value of phydev->supported is initialized by kernel.
So it includes many features that we do not support, such as
SUPPORTED_FIBRE and SUPPORTED_BNC. This patch fixes it.
Fixes: 256727d (net: hns3: Add MDIO support to HNS3 Ethernet driver for hip08 SoC)
