This device is 10Mbps half-duplex only, hence 51 * there is no media selection logic. The MAC supports a 128 entry 52 * multicast filter, though the exact size of the filter can depend 53 * on the firmware. Curiously, while the software spec describes various 54 * ethernet statistics counters, my sample adapter and firmware combination 55 * claims not to support any statistics counters at all. 56 * 57 * Note that once we load the firmware in the device, we have to be 58 * careful not to load it again: if you restart your computer but 59 * leave the adapter attached to the USB controller, it may remain 60 * powered on and retain its firmware. In this case, we don't need 61 * to load the firmware a second time. 62 * 63 * Special thanks to Rob Furr for providing an ADS Technologies 64 * adapter for development and testing. No monkeys were harmed during 65 * the development of this driver. 66 */ 67 68 /* 69 * Ported to NetBSD and somewhat rewritten by Lennart Augustsson. 70 */ 71 72 /* 73 * TODO: 74 * only use kue_do_request for downloading firmware. 75 * more DPRINTF 76 * proper cleanup on errors 77 */ 78 #if defined(__NetBSD__) || defined(__OpenBSD__) 79 #include "opt_inet.h" 80 #include "opt_ns.h" 81 #include "bpfilter.h" 82 #include "rnd.h" 83 #endif 84 85 #include <sys/param.h> 86 #include <sys/systm.h> 87 #include <sys/sockio.h> 88 #include <sys/mbuf.h> 89 #include <sys/malloc.h> 90 #include <sys/kernel.h> 91 #include <sys/socket.h> 92 93 #if defined(__FreeBSD__) 94 95 #include <net/ethernet.h> 96 #include <machine/clock.h> /* for DELAY */ 97 #include <sys/bus.h> 98 99 #elif defined(__NetBSD__) || defined(__OpenBSD__) 100 101 #include <sys/device.h> 102 103 #endif 104 105 #include <net/if.h> 106 #include <net/if_arp.h> 107 #include <net/if_dl.h> 108 109 #if defined(__NetBSD__) || defined(__OpenBSD__) 110 #include <net/if_ether.h> 111 112 #define bpf_mtap(ifp, m) bpf_tap((ifp)->if_bpf, mtod((m), caddr_t), (m)->m_len) 113 114 #endif 115 116 #if defined(__FreeBSD__) || NBPFILTER > 0 117 #include <net/bpf.h> 118 #endif 119 120 #if defined(__NetBSD__) || defined(__OpenBSD__) 121 #ifdef INET 122 #include <netinet/in.h> 123 #include <netinet/if_inarp.h> 124 #endif 125 126 #ifdef NS 127 #include <netns/ns.h> 128 #include <netns/ns_if.h> 129 #endif 130 #endif /* defined(__NetBSD__) || defined(__OpenBSD__) */ 131 132 #include <dev/usb/usb.h> 133 #include <dev/usb/usbdi.h> 134 #include <dev/usb/usbdi_util.h> 135 #include <dev/usb/usbdevs.h> 136 137 #ifdef __FreeBSD__ 138 #include <dev/usb/usb_ethersubr.h> 139 #endif 140 141 #include <dev/usb/if_kuereg.h> 142 #include <dev/usb/kue_fw.h> 143 144 #ifdef KUE_DEBUG 145 #define DPRINTF(x) if (kuedebug) logprintf x 146 #define DPRINTFN(n,x) if (kuedebug >= (n)) logprintf x 147 int kuedebug = 0;
