     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
     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.
