It is a filter that 40 * is roughly analogous to the "channel" setting with a garage 41 * door controller. Two companies side by side with wavelan devices 42 * that could actually hear each other can use different NWIDs 43 * and ignore packets. In truth however, the air space is shared, 44 * and the NWID is a virtual filter. 45 * 46 * In the current set of wavelan drivers, ioctls changed only 47 * the runtime radio modem registers which act in a manner analogous 48 * to an ethernet transceiver. The ioctls do not change the 49 * stored nvram PSA (or parameter storage area). At boot, the PSA 50 * values are stored in the radio modem. Thus when the 51 * system reboots it will restore the wavelan NWID to the value 52 * stored in the PSA. The NCR/ATT dos utilities must be used to 53 * change the initial NWID values in the PSA. The wlconfig utility 54 * may be used to set a different NWID at runtime; this is only 55 * permitted while the interface is up and running. 56 * 57 * By contrast, the IRQ value can only be changed while the 58 * Wavelan card is down and unconfigured, and it will remain 59 * disabled after an IRQ change until reboot. 60 * 61 */ 62 63#include <sys/param.h> 64#include <sys/socket.h> 65#include <sys/ioctl.h> 66#include <sys/time.h> 67#include <machine/if_wl_wavelan.h> 68 69#include <net/if.h> 70#include <netinet/in.h> 71#include <netinet/if_ether.h> 72 73#include <err.h> 74#include <stdio.h> 75#include <stdlib.h> 76#include <string.h> 77#include <unistd.h> 78#include <limits.h> 79 80/* translate IRQ bit to number */ 81/* array for maping irq numbers to values for the irq parameter register */ 82static int irqvals[16] = { 83 0, 0, 0, 0x01, 0x02, 0x04, 0, 0x08, 0, 0, 0x10, 0x20, 0x40, 0, 0, 0x80 84}; 85 86/* cache */ 87static int w_sigitems; /* count of valid items */ 88static struct w_sigcache wsc[MAXCACHEITEMS]; 89 90int 91wlirq(int irqval) 92{ 93 int irq; 94 95 for(irq = 0; irq < 16; irq++) 96 if(irqvals[irq] == irqval) 97 return(irq); 98 return 0; 99} 100 101char *compat_type[] = { 102 "PC-AT 915MHz", 103 "PC-MC 915MHz", 104 "PC-AT 2.4GHz", 105 "PC-MC 2.4GHz", 106 "PCCARD or 1/2 size AT, 915MHz or 2.4GHz" 107}; 108 109char *subband[] = { 110 "915MHz/see WaveModem", 111 "2425MHz", 112 "2460MHz", 113 "2484MHz", 114 "2430.5MHz" 115}; 116 117 118/* 119** print_psa 120** 121** Given a pointer to a PSA structure, print it out 122*/ 123void 124print_psa(u_char *psa, int currnwid) 125{ 126 int nwid; 127 128 /* 129 ** Work out what sort of board we have 130 */ 131 if (psa[0] == 0x14) { 132 printf("Board type : Microchannel\n"); 133 } else { 134 if (psa[1] == 0) { 135 printf("Board type : PCCARD\n"); 136 } else { 137 printf("Board type : ISA"); 138 if ((psa[4] == 0) && 139 (psa[5] == 0) && 140 (psa[6] == 0)) 141 printf(" (DEC OEM)"); 142 printf("\n"); 143 printf("Base address options : 0x300, 0x%02x0, 0x%02x0, 0x%02x0\n", 144 (int)psa[1], (int)psa[2], (int)psa[3]); 145 printf("Waitstates : %d\n",psa[7] & 0xf); 146 printf("Bus mode : %s\n",(psa[7] & 0x10) ?
