To communicate with the card a free 36 * command structure is filled in and then the card is interrupted. 37 * The card does the same with a different set of command structures. 38 * Only one command can be processed at a time. This is indicated 39 * by the interrupt having not been cleared since it was last set. 40 * The bit is cleared when the command has been processed (although 41 * it may not yet be complete). 42 * 43 * This driver was only tested with the Aviator 2.4 wireless 44 * The author didn't have the pro version or raylink to test 45 * with. 46 * 47 * N.B. Its unclear yet whether the Aviator 2.4 cards interoperate 48 * with other 802.11 FH 2Mbps cards, since this was also untested. 49 * Given the nature of the buggy build 4 firmware there may be problems. 50 * 51 * Authentication added by Steve Weiss <srw (at) alum.mit.edu> based on 52 * advice from Corey Thomas (author of the Linux RayLink driver). 53 * Authentication is currently limited to adhoc networks, and was 54 * added to support a requirement of the newest Windows drivers for 55 * the RayLink. Tested with Aviator Pro (firmware 5.63) on Win98. 56 */ 57 58 #include <sys/cdefs.h> 59 __KERNEL_RCSID(0, "$NetBSD: if_ray.c,v 1.41 2003/10/25 21:30:03 christos Exp $"); 60 61 #include "opt_inet.h" 62 #include "bpfilter.h" 63 64 #include <sys/param.h> 65 #include <sys/systm.h> 66 #include <sys/callout.h> 67 #include <sys/mbuf.h> 68 #include <sys/socket.h> 69 #include <sys/ioctl.h> 70 #include <sys/errno.h> 71 #include <sys/device.h> 72 #include <sys/kernel.h> 73 #include <sys/proc.h> 74 75 #include <net/if.h> 76 #include <net/if_dl.h> 77 #include <net/if_ether.h> 78 #include <net/if_media.h> 79 #include <net/if_llc.h> 80 #include <net80211/ieee80211.h> 81 #include <net80211/ieee80211_ioctl.h> 82 #include <net/if_media.h> 83 84 #ifdef INET 85 #include <netinet/in.h> 86 #include <netinet/in_systm.h> 87 #include <netinet/in_var.h> 88 #include <netinet/ip.h> 89 #include <netinet/if_inarp.h> 90 #endif 91 92 #if NBPFILTER > 0 93 #include <net/bpf.h> 94 #include <net/bpfdesc.h> 95 #endif 96 97 #include <machine/cpu.h> 98 #include <machine/bus.h> 99 #include <machine/intr.h> 100 101 #include <dev/pcmcia/pcmciareg.h> 102 #include <dev/pcmcia/pcmciavar.h> 103 #include <dev/pcmcia/pcmciadevs.h> 104 105 #include <dev/pcmcia/if_rayreg.h> 106 107 #define RAY_DEBUG 108 109 #ifndef RAY_PID_COUNTRY_CODE_DEFAULT 110 #define RAY_PID_COUNTRY_CODE_DEFAULT RAY_PID_COUNTRY_CODE_USA 111 #endif 112 113 /* amount of time to poll for non-return of certain command status */ 114 #ifndef RAY_CHECK_CCS_TIMEOUT 115 #define RAY_CHECK_CCS_TIMEOUT (hz / 2) 116 #endif 117 118 /* ammount of time to consider start/join failed */ 119 #ifndef RAY_START_TIMEOUT 120 #define RAY_START_TIMEOUT (30 * hz) 121 #endif 122 123 /* 124 * if a command cannot execute because device is busy try later 125 * this is also done after interrupts and other command timeouts 126 * so we can use a large value safely. 127 */ 128 #ifndef RAY_CHECK_SCHED_TIMEOUT 129 #define RAY_CHECK_SCHED_TIMEOUT (hz) /* XXX 5 */ 130 #endif 131 132 #ifndef RAY_MODE_DEFAULT 133 #define RAY_MODE_DEFAULT SC_MODE_ADHOC 134 #endif 135 136 #ifndef RAY_DEF_NWID 137 #define RAY_DEF_NWID "NETWORK_NAME" 138 #endif 139 140 /* 141 * The number of times the HW is reset in 30s before disabling. 142 * This is needed because resets take ~2s and currently pcmcia 143 * spins for the reset. 144 */ 145 #ifndef RAY_MAX_RESETS 146 #define RAY_MAX_RESETS 3 147 #endif 148 149 /* 150 * Types 151 */ 152 153 struct ray_softc { 154 struct device sc_dev;
