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