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 chipset supports only 10Mbps half-duplex mode, hence there are no ifmedia() modes to select.

For more information on configuring this device, see ifconfig(8).

BUGS

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