Datasheet is available 38 * from http://www.admtek.com.tw. 39 * 40 * Written by Bill Paul <wpaul (at) ee.columbia.edu> 41 * Electrical Engineering Department 42 * Columbia University, New York City 43 */ 44 45 /* 46 * The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet 47 * support: the control endpoint for reading/writing registers, burst 48 * read endpoint for packet reception, burst write for packet transmission 49 * and one for "interrupts." 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/lock.h> 92 #include <sys/mbuf.h> 93 #include <sys/malloc.h> 94 #include <sys/kernel.h> 95 #include <sys/socket.h> 96 97 #include <sys/device.h> 98 #if NRND > 0 99 #include <sys/rnd.h> 100 #endif 101 102 #include <net/if.h> 103 #if defined(__NetBSD__) 104 #include <net/if_arp.h> 105 #endif 106 #include <net/if_dl.h> 107 #include <net/if_media.h> 108 109 #define BPF_MTAP(ifp, m) bpf_mtap((ifp)->if_bpf, (m)) 110 111 #if NBPFILTER > 0 112 #include <net/bpf.h> 113 #endif 114 115 #if defined(__NetBSD__) 116 #include <net/if_ether.h> 117 #ifdef INET 118 #include <netinet/in.h> 119 #include <netinet/if_inarp.h> 120 #endif 121 #endif /* defined(__NetBSD__) */ 122 123 #if defined(__OpenBSD__) 124 #ifdef INET 125 #include <netinet/in.h> 126 #include <netinet/in_systm.h> 127 #include <netinet/in_var.h> 128 #include <netinet/ip.h> 129 #include <netinet/if_ether.h> 130 #endif 131 #endif /* defined(__OpenBSD__) */ 132 133 #ifdef NS 134 #include <netns/ns.h> 135 #include <netns/ns_if.h> 136 #endif 137 138 #include <dev/mii/mii.h> 139 #include <dev/mii/miivar.h> 140 141 #include <dev/usb/usb.h> 142 #include <dev/usb/usbdi.h> 143 #include <dev/usb/usbdi_util.h> 144 #include <dev/usb/usbdevs.h> 145 146 #include <dev/usb/if_auereg.h> 147 148 #ifdef AUE_DEBUG 149 #define DPRINTF(x) if (auedebug) logprintf x 150 #define DPRINTFN(n,x) if (auedebug >= (n)) logprintf x 151 int auedebug = 0;
