MEMBERS
  lan_media_mode
      Specifies the media mode. Typically, you set this member in the
      driver's probe interface to one of the following values, defined in
      <lan_common.h>:

      LAN_MEDIA_UTP
	  The mode for the media is unshielded twisted-pair cable.

      LAN_MEDIA_BNC
	  The mode for the media is thin wire.

      LAN_MEDIA_STP
	  The mode for the media is shielded twisted-pair cable.

      LAN_MEDIA_FIBER
	  The mode for the media is any fiber-based media.

      LAN_MEDIA_AUI
	  The mode for the media is the attachment unit interface (AUI).

      LAN_MEDIA_4PAIR
	  The mode for the media is 4-pair cable.

      LAN_MODE_AUTOSENSE
	  The mode for the media is autosense. This means the hardware
	  determines the media automatically.

  lan_media_state
      Specifies the media state. You set the lan_media_state member only if
      lan_media_mode is set to LAN_MODE_AUTOSENSE. You set this member in the
      driver's probe interface to one of the following constants, defined in
      <lan_common.h>:

      LAN_MEDIA_STATE_SENSING
	  The driver is trying to determine the media mode.

      LAN_MEDIA_STATE_DETERMINED
	  The media state has been determined.

  lan_media
      If lan_media_mode is set to lan_media_autosense, specifies the media
      mode that was set by the probe interface, as follows:

	·
	If lan_media_state is set to LAN_MEDIA_SENSING, the lan_media member
	contains the mode that the probe interface is currently testing. This
	value is not necessarily the media mode for the network device.

	·
	If lan_media_state is set to LAN_MEDIA_DETERMINED, the lan_media
	member contains the current media mode.	 That is, probe has
	successfully determined the media mode.

DESCRIPTION
  The lan_media data structure defines information related to the network
  medium. You typically declare an instance of the lan_media data structure
  in the network driver's softc data structure.
