/*
* wlconfig.c
*
* utility to read out and change various WAVELAN parameters.
* Currently supports NWID and IRQ values.
*
* The NWID is used by 2 or more wavelan controllers to determine
* if packets should be received or not. 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.
