39 * ADMtek AN986 Pegasus and AN8511 Pegasus II USB to ethernet driver.
40 * Datasheet is available from http://www.admtek.com.tw.
42 * Written by Bill Paul <wpaul@ee.columbia.edu>

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