.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 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 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 ,
and in
.Nx 1.5 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Bill Paul Aq wpaul@ee.columbia.edu .
.Sh BUGS
The
.Nm
driver does not accumulate ethernet collisions statistics because the
Kawasaki firmware does not appear to maintain any internal statistics.
