39 * ADMtek AN986 Pegasus and AN8511 Pegasus II USB to ethernet driver.
40 * Datasheet is available from http://www.admtek.com.tw.

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