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 uether_do_request(). Packet * transfers are done using usbd_transfer() and friends. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "usbdevs.h" #define USB_DEBUG_VAR aue_debug #include #include #include #include #ifdef USB_DEBUG static int aue_debug = 0;
