 * Note: For legacy March 2020 drivers (drivers with legacy_pre_march2020 set

 * in their &phylnk_config and which don't have a PCS), this function will be

 * called on each link up event, and to also change the in-band advert. For

 * non-legacy drivers, it will only be called to reconfigure the MAC for a

 * "major" change in e.g. interface mode. It will not be called for changes

 * in speed, duplex or pause modes or to change the in-band advertisement.

 * In any case, it is strongly preferred that speed, duplex and pause settings

 * are handled in the mac_link_up() method and not in this method.

 *

 * (this requires a rewrite - please refer to mac_link_up() for situations

 *  where the PCS and MAC are not tightly integrated.)

 * This will only be called to reconfigure the MAC for a "major" change in

 * e.g. interface mode. It will not be called for changes in speed, duplex

 * or pause modes or to change the in-band advertisement.

 *

 * In all negotiation modes, as defined by @mode, @state->pause indicates the

 * pause settings which should be applied as follows. If %MLO_PAUSE_AN is not

 *   1000base-X or Cisco SGMII mode depending on the @state->interface

 *   mode). In both cases, link state management (whether the link

 *   is up or not) is performed by the MAC, and reported via the

 *   mac_pcs_get_state() callback. Changes in link state must be made

 *   pcs_get_state() callback. Changes in link state must be made

 *   by calling phylink_mac_change().

 *

 *   Interface mode specific details are mentioned below.

 * in @state->link. If possible, @state->lp_advertising should also be
