47: * The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
48: * support: the control endpoint for reading/writing registers, burst
49: * read endpoint for packet reception, burst write for packet transmission
50: * and one for "interrupts." The chip uses the same RX filter scheme
51: * as the other ADMtek ethernet parts: one perfect filter entry for the
52: * the station address and a 64-bit multicast hash table. The chip supports
53: * both MII and HomePNA attachments.
54: *
55: * Since the maximum data transfer speed of USB is supposed to be 12Mbps,
56: * you're never really going to get 100Mbps speeds from this device. I
57: * think the idea is to allow the device to connect to 10 or 100Mbps
58: * networks, not necessarily to provide 100Mbps performance. Also, since
59: * the controller uses an external PHY chip, it's possible that board
60: * designers might simply choose a 10Mbps PHY.
61: *
62: * Registers are accessed using usbd_do_request(). Packet transfers are
63: * done using usbd_transfer() and friends.
