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 #if defined(__NetBSD__) 81 #include "opt_inet.h" 82 #include "opt_ns.h" 83 #include "bpfilter.h" 84 #include "rnd.h" 85 #elif defined(__OpenBSD__) 86 #include "bpfilter.h" 87 #endif /* defined(__OpenBSD__) */ 88 89 #include <sys/param.h> 90 #include <sys/systm.h> 91 #include <sys/sockio.h> 92 #include <sys/lock.h> 93 #include <sys/mbuf.h> 94 #include <sys/malloc.h> 95 #include <sys/kernel.h> 96 #include <sys/proc.h> 97 #include <sys/socket.h> 98 99 #include <sys/device.h> 100 #if NRND > 0 101 #include <sys/rnd.h> 102 #endif 103 104 #include <net/if.h> 105 #if defined(__NetBSD__) 106 #include <net/if_arp.h> 107 #endif 108 #include <net/if_dl.h> 109 #include <net/if_media.h> 110 111 #define BPF_MTAP(ifp, m) bpf_mtap((ifp)->if_bpf, (m)) 112 113 #if NBPFILTER > 0 114 #include <net/bpf.h> 115 #endif 116 117 #if defined(__NetBSD__) 118 #include <net/if_ether.h> 119 #ifdef INET 120 #include <netinet/in.h> 121 #include <netinet/if_inarp.h> 122 #endif 123 #endif /* defined(__NetBSD__) */ 124 125 #if defined(__OpenBSD__) 126 #ifdef INET 127 #include <netinet/in.h> 128 #include <netinet/in_systm.h> 129 #include <netinet/in_var.h> 130 #include <netinet/ip.h> 131 #include <netinet/if_ether.h> 132 #endif 133 #endif /* defined(__OpenBSD__) */ 134 135 #ifdef NS 136 #include <netns/ns.h> 137 #include <netns/ns_if.h> 138 #endif 139 140 #include <dev/mii/mii.h> 141 #include <dev/mii/miivar.h> 142 143 #include <dev/usb/usb.h> 144 #include <dev/usb/usbdi.h> 145 #include <dev/usb/usbdi_util.h> 146 #include <dev/usb/usbdevs.h> 147 148 #include <dev/usb/if_auereg.h> 149 150 #ifdef AUE_DEBUG 151 #define DPRINTF(x) if (auedebug) logprintf x 152 #define DPRINTFN(n,x) if (auedebug >= (n)) logprintf x 153 int auedebug = 0;
