DESCRIPTION    [Toc]    [Back]

     The aue driver provides support for USB ethernet adapters based on the
     ADMtek AN986 Pegasus chipset, including the following:

     +o	 Abocom UFE1000, DSB650TX_NA

     +o	 Accton USB320-EC, SpeedStream

     +o	 ADMtek AN986, AN8511

     +o	 Billionton USB100, USB100LP, USB100EL, USBE100

     +o	 Corega Ether FEther USB-T, FEther USB-TX, FEther USB-TXS

     +o	 D-Link DSB-650, DSB-650TX, DSB-650TX-PNA

     +o	 Elecom LD-USBL/TX

     +o	 Elsa Microlink USB2Ethernet

     +o	 I-O Data USB ETTX

     +o	 Kingston KNU101TX

     +o	 LinkSys USB10T adapters that contain the AN986 Pegasus chipset,
	 USB10TA, USB10TX, USB100TX, USB100H1

     +o	 MELCO LUA-TX, LUA2-TX

     +o	 Planex UE-200TX

     +o	 Siemens Speedstream

     +o	 SmartBridges smartNIC

     +o	 SMC 2202USB

     +o	 SOHOware NUB100

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

     The Pegasus contains a 10/100 ethernet MAC with MII interface and is
     designed to work with both ethernet and HomePNA transceivers.  Although
     designed 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 specifying
 full duplex implies half-duplex mode.

     100baseTX		   Set 100Mbps (fast ethernet) operation.  The
			   mediaopt option can also be used to enable
			   full-duplex operation.  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
			   operate in half duplex mode if this media option is
			   not specified.

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

DIAGNOSTICS    [Toc]    [Back]

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

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