Hi, This is my first mail to this list, I'm Pau from Barcelona working in guifi.net (wireless community) First of all I want to say thank you guys for your amazing job :-) Now, I have a little question. Using command "iw phy phy0 info" I can see that IBSS mode is only avaiable in some channels for 5ghz spectrum. I have been looking for information about it, but I cannot find from what depends if some channel can by used in IBSS mode or not. So I think it depends on the driver and on the regdomain, is it right? Also I'm working in some scripts, and I need to know if a channel has IBSS support or not. The only way I found is with iw command, but pharse this data is very dirty. Furthermore I can read in the end of iw help: "Do NOT screenscrape this tool, we don't consider its output stable." So I need another way to get this information. Any idea?
Copy bits of the wpa_supplicant or iw code into your code to get this information. That said, iw output _should_ be fairly stable, in this area. johannes
