37 * Kawasaki LSI KL5KUSB101B USB to ethernet adapter driver.
39 * Written by Bill Paul <wpaul@ee.columbia.edu>

41 * Columbia University, New York City
45 * The KLSI USB to ethernet adapter chip contains an USB serial interface,
46 * ethernet MAC and embedded microcontroller (called the QT Engine).
47 * The chip must have firmware loaded into it before it will operate.
48 * Packets are passed between the chip and host via bulk transfers.
49 * There is an interrupt endpoint mentioned in the software spec, however
50 * it's currently unused. This device is 10Mbps half-duplex only, hence
51 * there is no media selection logic. The MAC supports a 128 entry
52 * multicast filter, though the exact size of the filter can depend
53 * on the firmware. Curiously, while the software spec describes various
54 * ethernet statistics counters, my sample adapter and firmware combination
55 * claims not to support any statistics counters at all.
57 * Note that once we load the firmware in the device, we have to be
58 * careful not to load it again: if you restart your computer but
59 * leave the adapter attached to the USB controller, it may remain
60 * powered on and retain its firmware. In this case, we don't need
61 * to load the firmware a second time.
63 * Special thanks to Rob Furr for providing an ADS Technologies
64 * adapter for development and testing. No monkeys were harmed during
65 * the development of this driver.
