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. 64 */ 65 66 /* 67 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 68 */ 69 70 /* 71 * TODO: 72 * better error messages from rxstat 73 * split out if_auevar.h 74 * add thread to avoid register reads from interrupt context 75 * more error checks 76 * investigate short rx problem 77 * proper cleanup on errors 78 */ 79 80 #include "bpfilter.h" 81 82 #include <sys/param.h> 83 #include <sys/systm.h> 84 #include <sys/sockio.h> 85 #include <sys/rwlock.h> 86 #include <sys/mbuf.h> 87 #include <sys/kernel.h> 88 #include <sys/socket.h> 89 90 #include <sys/device.h> 91 92 #include <net/if.h> 93 #include <net/if_media.h> 94 95 #if NBPFILTER > 0 96 #include <net/bpf.h> 97 #endif 98 99 #include <netinet/in.h> 100 #include <netinet/if_ether.h> 101 102 #include <dev/mii/miivar.h> 103 104 #include <dev/usb/usb.h> 105 #include <dev/usb/usbdi.h> 106 #include <dev/usb/usbdi_util.h> 107 #include <dev/usb/usbdevs.h> 108 109 #include <dev/usb/if_auereg.h> 110 111 #ifdef AUE_DEBUG 112 #define DPRINTF(x) do { if (auedebug) printf x;
