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 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 automatic selection of the media type and
                           options.  The user can manually override the auto-
                           matically 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 spec-
                           ifying 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.
