+ADMtek AN986 Pegasus USB Ethernet driver
+.Sh SYNOPSIS
+.Cd "controller uhci0"
+.Cd "controller ohci0"
+.Cd "controller usb0"
+.Cd "controller miibus0"
+.Cd "device aue0"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB ethernet adapters based on the ADMtek
+AN986 Pegasus chipset, including the LinkSys USB100TX, the Billionton
+Systems USB100 and the Melco Inc. LU-ATX. 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.
+.Pp
+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.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It autoselect
+Enable autoselection of the media type and options.
+The user can manually override
+the autoselected mode by adding media options to the
+.Pa /etc/rc.conf
+file.
+.It 10baseT/UTP
+Set 10Mbps operation. The
+.Ar mediaopt
+option can also be used to enable
+.Ar full-duplex
+operation. Not specifying
+.Ar full duplex
+implies
+.Ar half-duplex
+mode.
+.It 100baseTX
+Set 100Mbps (fast ethernet) operation. The
+.Ar mediaopt
+option can also be used to enable
+.Ar full-duplex
+operation. Not specifying
+.Ar full duplex
+implies
+.Ar half-duplex
+mode.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
+.It full-duplex
+Force full duplex operation. The interface will operate in
+half duplex mode if this media option is not specified.
+.El
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "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.
+.It "aue%d: no memory for rx list"
+The driver failed to allocate an mbuf for the receiver ring.

+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Fx 4.0 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Bill Paul Aq wpaul@ee.columbia.edu .
+.Sh BUGS
+For some reason, outgoing bulk transfers (i.e. packet transmissions)
+fail if the transfer is exactly a multiple of 64 bytes in size. The
+.Nm
+driver works around this by padding such transfers up by one additional
+byte. This does not affect connectivity, however it does cause packets
+to occasionaly appear on the wire with one additional byte for no good
+reason. It is not known if this bug is due to a problem with Pegasus
+chip itself or some peculiarity of the underlying USB support.
