 38.Nd ADMtek AN986 Pegasus USB Ethernet driver
 39.Sh SYNOPSIS
 40To compile this driver into the kernel,
 41place the following lines in your
 42kernel configuration file:
 43.Bd -ragged -offset indent
 44.Cd "device uhci"
 45.Cd "device ohci"
 46.Cd "device usb"
 47.Cd "device miibus"
 48.Cd "device aue"
 49.Ed
 50.Pp
 51Alternatively, to load the driver as a
 52module at boot time, place the following line in
 53.Xr loader.conf 5 :
 54.Bd -literal -offset indent
 55if_aue_load="YES"
 56.Ed
 57.Sh DESCRIPTION
 58The
 59.Nm
 60driver provides support for USB Ethernet adapters based on the ADMtek
 61AN986 Pegasus chipset.
 62.Pp
 63The LinkSys USB10T adapters that contain the AN986 Pegasus chipset
 64will operate at 100Base-TX and full-duplex.
 65.Pp
 66The Pegasus contains a 10/100
 67Ethernet MAC with MII interface and is designed to work with both
 68Ethernet and HomePNA transceivers.
 69Although designed to interface with
 70100Mbps peripherals, the existing USB standard specifies a maximum
 71transfer speed of 12Mbps.
 72Users should therefore not expect to actually
 73achieve 100Mbps speeds with these devices.
 74.Pp
 75The Pegasus supports a 64-bit multicast hash table, single perfect
 76filter entry for the station address and promiscuous mode.
 77Packets are
 78received and transmitted over separate USB bulk transfer endpoints.
 79.Pp
 80The
 81.Nm
 82driver supports the following media types:
 83.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
 84.It autoselect
 85Enable autoselection of the media type and options.
 86The user can manually override
 87the autoselected mode by adding media options to the
 88.Pa /etc/rc.conf
 89file.
 90.It 10baseT/UTP
 91Set 10Mbps operation.
 92The
 93.Ar mediaopt
 94option can also be used to enable
 95.Ar full-duplex
 96operation.
 97Not specifying
 98.Ar full duplex
 99implies
100.Ar half-duplex
101mode.
102.It 100baseTX
103Set 100Mbps (Fast Ethernet) operation.
104The
105.Ar mediaopt
106option can also be used to enable
107.Ar full-duplex
108operation.
109Not specifying
110.Ar full duplex
111implies
112.Ar half-duplex
113mode.
114.El
115.Pp
116The
117.Nm
118driver supports the following media options:
119.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
120.It full-duplex
121Force full duplex operation.
122The interface will operate in
123half duplex mode if this media option is not specified.

178.It "aue%d: watchdog timeout"
179A packet was queued for transmission and a transmit command was
180issued, however the device failed to acknowledge the transmission
181before a timeout expired.
182.It "aue%d: no memory for rx list"
183The driver failed to allocate an mbuf for the receiver ring.
