kernel configuration file:
      device uhci
      device ohci
      device usb
      device kue
Alternatively,  to load the driver as a module at boot time,
place the

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, sin

gle 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 ifcon

fig(8).
