[ Upstream commit 2b39cabb2a283cea0c3d96d9370575371726164f ]
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.
Fixes: 496d03e (net: hns3: Add Ethtool support to HNS3 driver)
