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