| * @state->lp_advertising, @state->link, @state->an_complete are never |

| * |
| * 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 |

| * "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 |
