.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.

device driver first appeared in
.Fx 4.0 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Bill Paul Aq wpaul@ee.columbia.edu .

The
.Nm
driver does not accumulate ethernet collisions statistics because the
Kawasaki firmware does not appear to maintain any internal statistics.
