[ Upstream commit 5cd349c349d6ec52862e550d3576893d35ab8ac2 ]
Ethtool incorrectly reported supported and advertised auto-negotiation settings for a backplane PHY image which did not support auto-negotiation. This can occur when using media or PHY type for reporting ethtool supported and advertised auto-negotiation settings.
Remove setting supported and advertised auto-negotiation settings based on PHY type in ice_phy_type_to_ethtool(), and MAC type in ice_get_link_ksettings().
Ethtool supported and advertised auto-negotiation settings should be based on the PHY image using the AQ command get PHY capabilities with media. Add setting supported and advertised auto-negotiation settings based get PHY capabilities with media in ice_get_link_ksettings().
