| 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. |
