Hi Maxime I think the idea is good. I just have a few English language issues/questions. Capabilities is more often used than abilities. I just wondered if abilities is taken from the 802.3 specifications? Also, i wonder if we should include _pma_ in the name? At some point we might want to do something similar for other sublayers. > +/** > + * genphy_c45_read_abilities - read supported link modes from PMA > + * @phydev: target phy_device struct > + * > + * Read the supported link modes from the PMA Status 2 (1.8) register.
