NAME

kue - Kawasaki LSI KL5KUSB101B USB Ethernet driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device uhci device ohci device usb device kue

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

if_kue_load="YES"

DESCRIPTION

The ifconfig 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 chipset 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.

The ifconfig driver was written by An Bill Paul Aq wpaul@ee.columbia.edu .

BUGS

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