  The fast retrain and master slave seed configs are only applicable when
the 2.5G capability is supported.

Probably worth a comment - or a helper function.

E.g.

static bool qca808x_has_fast_retrain(struct phy_device *phydev)
{
	return linkmode_test_bit(ETHTOOL_LINK_MODE_2500baseT_Full_BIT,
				 phydev->supported);
}

Which then makes the code more self-documenting.
