> Thanks! Does it have any infrastructure for performing PSA modifications There is no need to modify the PSA. An interface to the running driver lets you set your NWID. But more likely, you should be "roaming" which dynimcally figures out the NWID you should be using. In our environment, the Wavelans do this. > (such as network ID) and support for monitoring signal strength? I assume There is an ioctl interface to bring out packets statistics and signal strength. And there is a program that prints them, analagous to vm_stat. I did not include either program in my uuencoded package. They are really simple and if you want to them let me know. > there is something for the latter since Dave Johnson is working on a Mobile > IP implementation for NetBSD! ;-) > > The current FreeBSD WaveLAN driver is based on the BSDI driver (Robert Morris' > port of Anders Klemets Mach driver).

It would be nice if we could spend our time on other > things! :-) This code is not based on Anders Klemets Mach driver. We did not like the copyright notice restrictions so we wrote a new driver. NCR Utrecht was pretty nice about giving us the specs. It supports a lot of what you are looking for like BPF and multicast, > > FYI: Roaming is link-level migration from one WavePoint to another. > WavePoints are bridges that provide a WaveLAN interface and an Ethernet True > interface.
