| 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. |
