No, but I mean, won't phylink call mt7531_mac_config(), mt753x_phylink_pcs_link_up()
and mt753x_phylink_mac_link_up() automatically and in the expected order already,
and if not, what prevents that from happening? I just don't understand why the
cpu_port_config() methods of MT7531 and MT7988 call phylink methods manually
from the driver.
