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.
The Kawasaki adapter supports only 10Mbps half-duplex mode, hence there are no ifmedia(4) modes to select.
For more information on configuring this device, see ifconfig(8).

FILES

The driver needs a firmware file, which is loaded on demand when the device is attached:
/etc/firmware/kue
 

DIAGNOSTICS

kue0: 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.
kue0: no memory for rx list
The driver failed to allocate an mbuf for the receiver ring.

HISTORY

The kue device driver first appeared in FreeBSD 4.0. OpenBSD support was added in OpenBSD 2.7.

AUTHORS

The kue driver was written by Bill Paul <wpaul@ee.columbia.edu> and ported to OpenBSD by Aaron Campbell <aaron@openbsd.org>.

BUGS

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