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