To communicate with the card a free 37 * command structure is filled in and then the card is interrupted. 38 * The card does the same with a different set of command structures. 39 * Only one command can be processed at a time. This is indicated 40 * by the interrupt having not been cleared since it was last set. 41 * The bit is cleared when the command has been processed (although 42 * it may not yet be complete). 43 * 44 * This driver was only tested with the Aviator 2.4 wireless 45 * The author didn't have the pro version or raylink to test 46 * with. 47 * 48 * N.B. Its unclear yet whether the Aviator 2.4 cards interoperate 49 * with other 802.11 FH 2Mbps cards, since this was also untested. 50 * Given the nature of the buggy build 4 firmware there may be problems. 51 * 52 * Authentication added by Steve Weiss <srw@alum.mit.edu> based on 53 * advice from Corey Thomas (author of the Linux RayLink driver). 54 * Authentication is currently limited to adhoc networks, and was 55 * added to support a requirement of the newest Windows drivers for 56 * the RayLink. Tested with Aviator Pro (firmware 5.63) on Win98. 57 */ 58 59 #include <sys/cdefs.h> 60 __KERNEL_RCSID(0, "$NetBSD: if_ray.c,v 1.70 2008/04/05 21:31:23 cegger Exp $"); 61 62 #include "opt_inet.h" 63 #include "bpfilter.h" 64 65 #include <sys/param.h> 66 #include <sys/systm.h> 67 #include <sys/callout.h> 68 #include <sys/mbuf.h> 69 #include <sys/socket.h> 70 #include <sys/ioctl.h> 71 #include <sys/errno.h> 72 #include <sys/device.h> 73 #include <sys/kernel.h> 74 #include <sys/proc.h> 75 76 #include <net/if.h> 77 #include <net/if_dl.h> 78 #include <net/if_ether.h> 79 #include <net/if_media.h> 80 #include <net/if_llc.h> 81 #include <net80211/ieee80211.h> 82 #include <net80211/ieee80211_ioctl.h> 83 #include <net/if_media.h> 84 85 #ifdef INET 86 #include <netinet/in.h> 87 #include <netinet/in_systm.h> 88 #include <netinet/in_var.h> 89 #include <netinet/ip.h> 90 #include <netinet/if_inarp.h> 91 #endif 92 93 #if NBPFILTER > 0 94 #include <net/bpf.h> 95 #include <net/bpfdesc.h> 96 #endif 97 98 #include <sys/cpu.h> 99 #include <sys/bus.h> 100 #include <sys/intr.h> 101 102 #include <dev/pcmcia/pcmciareg.h> 103 #include <dev/pcmcia/pcmciavar.h> 104 #include <dev/pcmcia/pcmciadevs.h> 105 106 #include <dev/pcmcia/if_rayreg.h> 107 108 #define RAY_DEBUG 109 110 #ifndef RAY_PID_COUNTRY_CODE_DEFAULT 111 #define RAY_PID_COUNTRY_CODE_DEFAULT RAY_PID_COUNTRY_CODE_USA 112 #endif 113 114 /* amount of time to poll for non-return of certain command status */ 115 #ifndef RAY_CHECK_CCS_TIMEOUT 116 #define RAY_CHECK_CCS_TIMEOUT (hz / 2) 117 #endif 118 119 /* ammount of time to consider start/join failed */ 120 #ifndef RAY_START_TIMEOUT 121 #define RAY_START_TIMEOUT (30 * hz) 122 #endif 123 124 /* 125 * if a command cannot execute because device is busy try later 126 * this is also done after interrupts and other command timeouts 127 * so we can use a large value safely. 128 */ 129 #ifndef RAY_CHECK_SCHED_TIMEOUT 130 #define RAY_CHECK_SCHED_TIMEOUT (hz) /* XXX 5 */ 131 #endif 132 133 #ifndef RAY_MODE_DEFAULT 134 #define RAY_MODE_DEFAULT SC_MODE_ADHOC 135 #endif 136 137 #ifndef RAY_DEF_NWID 138 #define RAY_DEF_NWID "NETWORK_NAME" 139 #endif 140 141 /* 142 * The number of times the HW is reset in 30s before disabling. 143 * This is needed because resets take ~2s and currently pcmcia 144 * spins for the reset. 145 */ 146 #ifndef RAY_MAX_RESETS 147 #define RAY_MAX_RESETS 3 148 #endif 149 150 /* 151 * Types 152 */ 153 154 struct ray_softc { 155 struct device sc_dev;
