[PATCH net] net: phy: motorcomm: read EEE abilities in yt8521_get_features()

[xiaoning . wang]

From: Clark Wang <xiaoning.wang@xxxxxxx>

In phy_probe(), genphy_c45_read_eee_abilities() is only called when a
driver uses phydrv->features. Drivers that implement .get_features are
responsible for reading the EEE abilities themselves.

yt8521_get_features() does not do this, so phydev->supported_eee stays
empty for YT8521/YT8531S and "ethtool --show-eee" reports "EEE status:
not supported", even though the PHY has the standard EEE capability
registers.

Call genphy_c45_read_eee_abilities() at the end of yt8521_get_features()
to populate supported_eee.
