DESCRIPTION

     The kue driver provides support for USB Ethernet adapters based on the
     Kawasaki LSI KL5KLUSB101B chipset.

     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).


DIAGNOSTICS

     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.

     kue%d: 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, and in NetBSD 1.5.


AUTHORS

     The kue driver was written by Bill Paul <wpaul@ee.columbia.edu>.


BUGS

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