NAME
     aue -- ADMtek AN986 Pegasus USB Ethernet driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device uhci
	   device ohci
	   device usb
	   device miibus
	   device aue

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_aue_load="YES"

DESCRIPTION
     The  aue  driver  provides  support  for USB Ethernet adapters based on the
     ADMtek AN986 Pegasus chipset.

     The LinkSys USB10T adapters that contain the AN986 Pegasus chipset will op-
     erate at 100Base-TX and full-duplex.

     The Pegasus contains a 10/100 Ethernet MAC with MII interface  and  is  de-
     signed  to  work with both Ethernet and HomePNA transceivers.  Although de-
     signed to interface with 100Mbps peripherals,  the  existing  USB	standard
     specifies	a  maximum transfer speed of 12Mbps.  Users should therefore not
     expect to actually achieve 100Mbps speeds with these devices.

     The Pegasus supports a 64-bit multicast hash table, single  perfect  filter
     entry  for  the station address and promiscuous mode.  Packets are received
     and transmitted over separate USB bulk transfer endpoints.

     The aue driver supports the following media types:

     autoselect 	   Enable autoselection of the media type  and	options.
			   The	user can manually override the autoselected mode
			   by adding media options to the /etc/rc.conf file.

     10baseT/UTP	   Set 10Mbps operation.  The mediaopt option  can  also
			   be  used to enable full-duplex operation.  Not speci-
			   fying full duplex implies half-duplex mode.

     100baseTX		   Set 100Mbps (Fast Ethernet) operation.  The	mediaopt
			   option  can also be used to enable full-duplex opera-
			   tion.  Not specifying full duplex implies half-duplex
			   mode.

     The aue driver supports the following media options:

     full-duplex	   Force full duplex operation.  The interface will  op-
			   erate in half duplex mode if this media option is not
			   specified.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS
     aue%d: watchdog timeout  A packet was queued for transmission and a  trans-
     mit command was issued, however the device failed to acknowledge the trans-
     mission before a timeout expired.

     aue%d: no memory for rx list  The driver failed to allocate an mbuf for the
     receiver ring.
