DESCRIPTION

     The aue driver provides support for USB Ethernet adapters based on the ADMtek AN986 Pegasus and AN8511 Pegasus II chipsets.

     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 there-
     fore 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 automatic selection of the media type and options.  The user can manually override the automatically selected
			   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

     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.
