 * @state->lp_advertising, @state->link, @state->an_complete are never
 * guaranteed to be correct, and so any mac_config() implementation must
 * never reference these fields.
 *
 * 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.)
 *
 * 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
 * set, %MLO_PAUSE_TX and %MLO_PAUSE_RX indicate whether the MAC should send
 * pause frames and/or act on received pause frames respectively. Otherwise,
 * the results of in-band negotiation/status from the MAC PCS should be used
 * to control the MAC pause mode settings.
 *
 * The action performed depends on the currently selected mode:
 *
 * %MLO_AN_FIXED, %MLO_AN_PHY:
 *   Configure for non-inband negotiation mode, where the link settings
 *   are completely communicated via mac_link_up().  The physical link
 *   protocol from the MAC is specified by @state->interface.
 *
 *   @state->advertising may be used, but is not required.
 *
 *   Older drivers (prior to the mac_link_up() change) may use @state->speed,
 *   @state->duplex and @state->pause to configure the MAC, but this is
 *   deprecated; such drivers should be converted to use mac_link_up().
 *
 *   Other members of @state must be ignored.
 *
 *   Valid state members: interface, advertising.
 *   Deprecated state members: speed, duplex, pause.
 *
 * %MLO_AN_INBAND:
 *   place the link in an inband negotiation mode (such as 802.3z
 *   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
 *   by calling phylink_mac_change().
 *
 *   Interface mode specific details are mentioned below.
 *
 *   If in 802.3z mode, the link speed is fixed, dependent on the
 *   @state->interface. Duplex and pause modes are negotiated via
 *   the in-band configuration word. Advertised pause modes are set
 *   according to the @state->an_enabled and @state->advertising
 *   flags. Beware of MACs which only support full duplex at gigabit
 *   and higher speeds.
 *
 *   If in Cisco SGMII mode, the link speed and duplex mode are passed
 *   in the serial bitstream 16-bit configuration word, and the MAC
 *   should be configured to read these bits and acknowledge the
 *   configuration word. Nothing is advertised by the MAC. The MAC is
 *   responsible for reading the configuration word and configuring
 *   itself accordingly.
 *
 *   Valid state members: interface, an_enabled, pause, advertising.
 *
 * Implementations are expected to update the MAC to reflect the
 * requested settings - i.o.w., if nothing has changed between two
 * calls, no action is expected.  If only flow control settings have
 * changed, flow control should be updated *without* taking the link
 * down.  This "update" behaviour is critical to avoid bouncing the
 * link up status.
