- *
- * (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

- * 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
