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