Subject: net: hns3: fix for getting advertised_caps in hns3_get_link_ksettings
Patch-mainline: v4.15-rc1
Git-commit: 2b39cabb2a283cea0c3d96d9370575371726164f
References: bsc#1104353 FATE#326415
This patch fixes a bug for ethtool's get_link_ksettings().
The advertising for autoneg is always added to advertised_caps
whether autoneg is enable or disable. This patch fixes it.
