/*
* The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
* support: the control endpoint for reading/writing registers, burst
* read endpoint for packet reception, burst write for packet transmission
* and one for "interrupts." The chip uses the same RX filter scheme
* as the other ADMtek ethernet parts: one perfect filter entry for the
* the station address and a 64-bit multicast hash table. The chip supports
* both MII and HomePNA attachments.
*
* Since the maximum data transfer speed of USB is supposed to be 12Mbps,
* you're never really going to get 100Mbps speeds from this device. I
* think the idea is to allow the device to connect to 10 or 100Mbps
* networks, not necessarily to provide 100Mbps performance. Also, since
* the controller uses an external PHY chip, it's possible that board
* designers might simply choose a 10Mbps PHY.
*
* Registers are accessed using usb2_do_request(). Packet transfers are
* done using usb2_transfer() and friends.
