The chip uses the same RX filter scheme 50 * as the other ADMtek ethernet parts: one perfect filter entry for the 51 * the station address and a 64-bit multicast hash table. The chip supports 52 * both MII and HomePNA attachments. 53 * 54 * Since the maximum data transfer speed of USB is supposed to be 12Mbps, 55 * you're never really going to get 100Mbps speeds from this device. I 56 * think the idea is to allow the device to connect to 10 or 100Mbps 57 * networks, not necessarily to provide 100Mbps performance. Also, since 58 * the controller uses an external PHY chip, it's possible that board 59 * designers might simply choose a 10Mbps PHY. 60 * 61 * Registers are accessed using usb2_do_request(). Packet transfers are 62 * done using usb2_transfer() and friends. 63 */ 64 65/* 66 * NOTE: all function names beginning like "aue_cfg_" can only 67 * be called from within the config thread function !
