### 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.

### SEE ALSO

arp(4), netintro(4), usb(4), ifconfig(8)

### HISTORY

The kue device driver first appeared in FreeBSD4.0, and in NetBSD1.5.

### 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 statistics.
