It is a filter that + * is roughly analogous to the "channel" setting with a garage + * door controller. Two companies side by side with wavelan devices + * that could actually hear each other can use different NWIDs + * and ignore packets. In truth however, the air space is shared, + * and the NWID is a virtual filter. + * + * In the current set of wavelan drivers, ioctls changed only + * the runtime radio modem registers which act in a manner analogous + * to an ethernet transceiver. The ioctls do not change the + * stored nvram PSA (or parameter storage area). At boot, the PSA + * values are stored in the radio modem. Thus when the + * system reboots it will restore the wavelan NWID to the value + * stored in the PSA. The NCR/ATT dos utilities must be used to + * change the initial NWID values in the PSA. The wlconfig utility + * may be used to set a different NWID at runtime; this is only + * permitted while the interface is up and running. + * + * By contrast, the IRQ value can only be changed while the + * Wavelan card is down and unconfigured, and it will remain + * disabled after an IRQ change until reboot. + * + */ + +#include <sys/param.h> +#include <sys/socket.h> +#include <sys/ioctl.h> +#include <machine/if_wl_wavelan.h> + +#include <net/if.h> +#include <netinet/in.h> +#include <netinet/if_ether.h> +extern struct ether_addr *ether_aton(char *a); + +#include <err.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <unistd.h> +#include <limits.h> + +/* translate IRQ bit to number */ +/* array for maping irq numbers to values for the irq parameter register */ +static int irqvals[16] = { + 0, 0, 0, 0x01, 0x02, 0x04, 0, 0x08, 0, 0, 0x10, 0x20, 0x40, 0, 0, 0x80 +}; + +int +wlirq(int irqval) +{ + int irq; + + for(irq = 0; irq < 16; irq++) + if(irqvals[irq] == irqval) + return(irq); + return 0; +} + +char *compat_type[] = { + "PC-AT 915MHz", + "PC-MC 915MHz", + "PC-AT 2.4GHz", + "PC-MC 2.4GHz", + "PCCARD or 1/2 size AT, 915MHz or 2.4GHz" +}; + +char *subband[] = { + "915MHz/see WaveModem", + "2425MHz", + "2460MHz", + "2484MHz", + "2430.5MHz" +}; + + +/* +** print_psa +** +** Given a pointer to a PSA structure, print it out +*/ +void +print_psa(u_char *psa, int currnwid) +{ + int nwid; + + /* + ** Work out what sort of board we have + */ + if (psa[0] == 0x14) { + printf("Board type : Microchannel\n"); + } else { + if (psa[1] == 0) { + printf("Board type : PCCARD\n"); + } else { + printf("Board type : ISA"); + if ((psa[4] == 0) && + (psa[5] == 0) && + (psa[6] == 0)) + printf(" (DEC OEM)"); + printf("\n"); + printf("Base address options : 0x300, 0x%02x0, 0x%02x0, 0x%02x0\n", + (int)psa[1], (int)psa[2], (int)psa[3]); + printf("Waitstates : %d\n",psa[7] & 0xf); + printf("Bus mode : %s\n",(psa[7] & 0x10) ?
