The chip uses the same RX filter scheme + * as the other ADMtek ethernet parts: one perfect filter entry for the + * the station address and a 64-bit multicast hash table. The chip supports + * both MII and HomePNA attachments. + * + * Since the maximum data transfer speed of USB is supposed to be 12Mbps, + * you're never really going to get 100Mbps speeds from this device. I + * think the idea is to allow the device to connect to 10 or 100Mbps + * networks, not necessarily to provide 100Mbps performance. Also, since + * the controller uses an external PHY chip, it's possible that board + * designers might simply choose a 10Mbps PHY. + * + * Registers are accessed using usbd_do_request().
