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