287 * Note: For legacy March 2020 drivers (drivers with legacy_pre_march2020 set
288 * in their &phylnk_config and which don't have a PCS), this function will be
289 * called on each link up event, and to also change the in-band advert. For

291 * "major" change in e.g. interface mode. It will not be called for changes
292 * in speed, duplex or pause modes or to change the in-band advertisement.
293 * In any case, it is strongly preferred that speed, duplex and pause settings

301 * set, %MLO_PAUSE_TX and %MLO_PAUSE_RX indicate whether the MAC should send
302 * pause frames and/or act on received pause frames respectively. Otherwise,
303 * the results of in-band negotiation/status from the MAC PCS should be used
304 * to control the MAC pause mode settings.

310 * are completely communicated via mac_link_up(). The physical link
311 * protocol from the MAC is specified by @state->interface.
313 * @state->advertising may be used, but is not required.
315 * Older drivers (prior to the mac_link_up() change) may use @state->speed,
316 * @state->duplex and @state->pause to configure the MAC, but this is
317 * deprecated; such drivers should be converted to use mac_link_up().
319 * Other members of @state must be ignored.
321 * Valid state members: interface, advertising.
322 * Deprecated state members: speed, duplex, pause.
325 * place the link in an inband negotiation mode (such as 802.3z
326 * 1000base-X or Cisco SGMII mode depending on the @state->interface
327 * mode). In both cases, link state management (whether the link
328 * is up or not) is performed by the MAC, and reported via the
329 * mac_pcs_get_state() callback. Changes in link state must be made
330 * by calling phylink_mac_change().
332 * Interface mode specific details are mentioned below.
334 * If in 802.3z mode, the link speed is fixed, dependent on the
335 * @state->interface. Duplex and pause modes are negotiated via
336 * the in-band configuration word. Advertised pause modes are set
337 * according to the @state->an_enabled and @state->advertising
338 * flags. Beware of MACs which only support full duplex at gigabit
341 * If in Cisco SGMII mode, the link speed and duplex mode are passed
342 * in the serial bitstream 16-bit configuration word, and the MAC
343 * should be configured to read these bits and acknowledge the
344 * configuration word. Nothing is advertised by the MAC. The MAC is
345 * responsible for reading the configuration word and configuring
346 * itself accordingly.
348 * Valid state members: interface, an_enabled, pause, advertising.
350 * Implementations are expected to update the MAC to reflect the
351 * requested settings - i.o.w., if nothing has changed between two
352 * calls, no action is expected. If only flow control settings have
353 * changed, flow control should be updated *without* taking the link
