.Nd "Kawasaki LSI KL5KUSB101B USB Ethernet driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device uhci"
|
|
.Cd "device ohci"
|

.Cd "device miibus"
|
|
.Cd "device uether"
|
|
.Cd "device kue"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for USB Ethernet adapters based on the Kawasaki
|
|
LSI KL5KLUSB101B chipset.
|
|
.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 chipset supports only 10Mbps half-duplex mode, hence there
|
|
are no
|
|
.Fn ifmedia
|
|
modes to select.
|
|
.Pp
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .

|
|
.Sh AUTHORS
|
|
The
|
|

.An Bill Paul Aq Mt wpaul@ee.columbia.edu .
|
|
.Sh BUGS

|
|
driver does not accumulate Ethernet collisions statistics because the
|
|
Kawasaki firmware does not appear to maintain any internal statistics.
