38  * Register definitions for ADMtek Pegasus AN986 USB to Ethernet
39  * chip. The Pegasus uses a total of four USB endpoints: the control
40  * endpoint (0), a bulk read endpoint for receiving packets (1),
41  * a bulk write endpoint for sending packets (2) and an interrupt
42  * endpoint for passing RX and TX status (3). Endpoint 0 is used
43  * to read and write the ethernet module's registers. All registers
44  * are 8 bits wide.
45  *
46  * Packet transfer is done in 64 byte chunks. The last chunk in a
47  * transfer is denoted by having a length less that 64 bytes. For
48  * the RX case, the data includes an optional RX status word.

60  * regarded as special by the USB code and drivers
61  * don't have direct access to it. (We access it
62  * using usbd_do_request() when reading/writing
63  * registers.) Consequently, our endpoint indexes
64  * don't match those in the ADMtek Pegasus manual:
65  * we consider the RX data endpoint to be index 0
66  * and work up from there.
