.Sh SYNOPSIS
.Cd "aue*   at uhub? port ?"
.Cd "ukphy* at mii?"
.Sh DESCRIPTION
The
.Nm
driver provides support for USB Ethernet adapters based on the ADMtek
AN986 Pegasus chipset.
This includes the following adapters:

.El
.Pp
The
.Nm
driver provides support for USB
.Tn Ethernet
adapters based on the ADMtek AN986 Pegasus chipset.
.Pp
The Pegasus contains a 10/100
.Tn Ethernet
MAC with MII interface and is designed to work with both
.Tn 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 appropriate
.Xr hostname.if 5
file.
.It 10baseT
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
.Tn 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.
