net: hns3: fix a bug for phy supported feature initialization
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) Signed-off-by: Fuyun Liang <liangfuyun1@huawei.com> Signed-off-by: Lipeng <lipeng321@huawei.com> Signed-off-by: David S.
