42 * ADMtek AN986 Pegasus and AN8511 Pegasus II USB to ethernet driver.

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