.Sh DESCRIPTION
The
.Nm
driver provides support for USB Ethernet adapters based on the Kawasaki
LSI KL5KLUSB101B chipset.
This includes the following adapters:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Tn 3Com 3c19250
.It Tn 3Com 3c460 HomeConnect
.It Tn AboCom Systems URE450 Ethernet
.It Tn ADS Technologies USB-10BT
.It Tn Aox USB101
.It Tn ATen UC10T
.It Tn ATen DSB-650C
.It Tn Corega USB-T
.It Tn D-Link DSB-650C
.It Tn Entrega NET-USB-E45
.It Tn I/O Data USB-ET/T
.It Tn Kingston Ethernet
.It Tn Kawasaki USB101
.It Tn LinkSys USB10T
.It Tn Mobility Ethernet
.It Tn Netgear EA101
.It Tn Peracom USB
.It Tn Portgear Ethernet
.It Tn Portsmith Express Ethernet
.It Tn Shark Pocket Adapter
.It Tn Silicom U2E
.It Tn SMC 2102USB
.It Tn SMC 2104USB
.El
.Pp
The KL5KLUSB101B supports a 128-entry multicast filter, single perfect
filter entry for the station address and promiscuous mode.
Packets are
received and transmitted over separate USB bulk transfer endpoints.
.Pp
The Kawasaki adapter supports only 10Mbps half-duplex mode, hence there
are no
.Xr ifmedia 4
modes to select.
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh FILES
The driver need a firmware file,
which is loaded on demand when the device is attached:
.Pp
.Bl -tag -width Ds -offset indent -compact
.It Pa /etc/firmware/kue
.El
.Sh DIAGNOSTICS
.Bl -diag
.It "kue%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 "kue%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 .
.Ox
support was added in
.Ox 2.7 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Bill Paul Aq wpaul@ee.columbia.edu
and ported to
