It is a filter that 37 * is roughly analogous to the "channel" setting with a garage 38 * door controller. Two companies side by side with wavelan devices 39 * that could actually hear each other can use different NWIDs 40 * and ignore packets. In truth however, the air space is shared, 41 * and the NWID is a virtual filter. 42 * 43 * In the current set of wavelan drivers, ioctls changed only 44 * the runtime radio modem registers which act in a manner analogous 45 * to an ethernet transceiver. The ioctls do not change the 46 * stored nvram PSA (or parameter storage area). At boot, the PSA 47 * values are stored in the radio modem. Thus when the 48 * system reboots it will restore the wavelan NWID to the value 49 * stored in the PSA. The NCR/ATT dos utilities must be used to 50 * change the initial NWID values in the PSA. The wlconfig utility 51 * may be used to set a different NWID at runtime; this is only 52 * permitted while the interface is up and running. 53 * 54 * By contrast, the IRQ value can only be changed while the 55 * Wavelan card is down and unconfigured, and it will remain 56 * disabled after an IRQ change until reboot. 57 * 58 */ 59 60#include <sys/param.h> 61#include <sys/socket.h> 62#include <sys/ioctl.h> 63#include <machine/if_wl_wavelan.h> 64 65#include <net/if.h> 66#include <netinet/in.h> 67#include <netinet/if_ether.h> 68extern struct ether_addr *ether_aton(char *a); 69 70#include <err.h> 71#include <stdio.h> 72#include <stdlib.h> 73#include <string.h> 74#include <unistd.h> 75#include <limits.h> 76 77/* translate IRQ bit to number */ 78/* array for maping irq numbers to values for the irq parameter register */ 79static int irqvals[16] = { 80 0, 0, 0, 0x01, 0x02, 0x04, 0, 0x08, 0, 0, 0x10, 0x20, 0x40, 0, 0, 0x80 81}; 82 83int 84wlirq(int irqval) 85{ 86 int irq; 87 88 for(irq = 0; irq < 16; irq++) 89 if(irqvals[irq] == irqval) 90 return(irq); 91 return 0; 92} 93 94char *compat_type[] = { 95 "PC-AT 915MHz", 96 "PC-MC 915MHz", 97 "PC-AT 2.4GHz", 98 "PC-MC 2.4GHz", 99 "PCCARD or 1/2 size AT, 915MHz or 2.4GHz" 100}; 101 102char *subband[] = { 103 "915MHz/see WaveModem", 104 "2425MHz", 105 "2460MHz", 106 "2484MHz", 107 "2430.5MHz" 108}; 109 110 111/* 112** print_psa 113** 114** Given a pointer to a PSA structure, print it out 115*/ 116void 117print_psa(u_char *psa, int currnwid) 118{ 119 int nwid; 120 121 /* 122 ** Work out what sort of board we have 123 */ 124 if (psa[0] == 0x14) { 125 printf("Board type : Microchannel\n"); 126 } else { 127 if (psa[1] == 0) { 128 printf("Board type : PCCARD\n"); 129 } else { 130 printf("Board type : ISA"); 131 if ((psa[4] == 0) && 132 (psa[5] == 0) && 133 (psa[6] == 0)) 134 printf(" (DEC OEM)"); 135 printf("\n"); 136 printf("Base address options : 0x300, 0x%02x0, 0x%02x0, 0x%02x0\n", 137 (int)psa[1], (int)psa[2], (int)psa[3]); 138 printf("Waitstates : %d\n",psa[7] & 0xf); 139 printf("Bus mode : %s\n",(psa[7] & 0x10) ?
