 *   Configure the specified @state->speed, @state->duplex and
 *   @state->pause (%MLO_PAUSE_TX / %MLO_PAUSE_RX) modes over a link

 *
 * %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

 *   by calling phylink_mac_change().
 *
 *   If in 802.3z mode, the link speed is fixed, dependent on the
 *   @state->interface. Duplex is negotiated, and pause is advertised
 *   according to @state->an_enabled, @state->pause 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

 *   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
