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 usbd_do_request(). Packet transfers are 62 * done using usbd_transfer() and friends. 63 */ 64 65 /* 66 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 67 */ 68 69 /* 70 * TODO: 71 * better error messages from rxstat 72 * split out if_auevar.h 73 * add thread to avoid register reads from interrupt context 74 * more error checks 75 * investigate short rx problem 76 * proper cleanup on errors 77 */ 78 79 #if defined(__NetBSD__) 80 #include "opt_inet.h" 81 #include "opt_ns.h" 82 #include "bpfilter.h" 83 #include "rnd.h" 84 #elif defined(__OpenBSD__) 85 #include "bpfilter.h" 86 #endif /* defined(__OpenBSD__) */ 87 88 #include <sys/param.h> 89 #include <sys/systm.h> 90 #include <sys/sockio.h> 91 #include <sys/mbuf.h> 92 #include <sys/malloc.h> 93 #include <sys/kernel.h> 94 #include <sys/socket.h> 95 96 #include <sys/device.h> 97 #if NRND > 0 98 #include <sys/rnd.h> 99 #endif 100 101 #include <net/if.h> 102 #if defined(__NetBSD__) 103 #include <net/if_arp.h> 104 #endif 105 #include <net/if_dl.h> 106 #include <net/if_media.h> 107 108 #define BPF_MTAP(ifp, m) bpf_mtap((ifp)->if_bpf, (m)) 109 110 #if NBPFILTER > 0 111 #include <net/bpf.h> 112 #endif 113 114 #if defined(__NetBSD__) 115 #include <net/if_ether.h> 116 #ifdef INET 117 #include <netinet/in.h> 118 #include <netinet/if_inarp.h> 119 #endif 120 #endif /* defined(__NetBSD__) */ 121 122 #if defined(__OpenBSD__) 123 #ifdef INET 124 #include <netinet/in.h> 125 #include <netinet/in_systm.h> 126 #include <netinet/in_var.h> 127 #include <netinet/ip.h> 128 #include <netinet/if_ether.h> 129 #endif 130 #endif /* defined(__OpenBSD__) */ 131 132 #ifdef NS 133 #include <netns/ns.h> 134 #include <netns/ns_if.h> 135 #endif 136 137 #include <dev/mii/mii.h> 138 #include <dev/mii/miivar.h> 139 140 #include <dev/usb/usb.h> 141 #include <dev/usb/usbdi.h> 142 #include <dev/usb/usbdi_util.h> 143 #include <dev/usb/usbdevs.h> 144 145 #include <dev/usb/if_auereg.h> 146 147 #ifdef AUE_DEBUG 148 #define DPRINTF(x) if (auedebug) logprintf x 149 #define DPRINTFN(n,x) if (auedebug >= (n)) logprintf x 150 int auedebug = 0;
