Subject: [PATCH net-next] net: dsa: sja1105: move MAC configuration to
 .phylink_mac_link_up

From: Vladimir Oltean <olteanv@...il.com>

The switches supported so far by the driver only have non-SerDes ports,
so they should be configured in the PHYLINK callback that provides the
resolved PHY link parameters.
