/*
|
|
* 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.
