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