     The Pegasus family of chipsets contain a 10/100 Ethernet MAC
with an MII
     interface and are designed to work with  both  Ethernet  and
HomePNA
     transceivers.   Although the chipsets are designed to interface with
     100Mbps peripherals, the USB 1.x standards specify a maximum
transfer
     speed of 12Mbps.  Users should therefore not expect to actually achieve
     100Mbps speeds with these devices.

     The Pegasus chipsets support 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 appropriate hostname.if(5) file.

     10baseT     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.
