IBSS channel support
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?
Thank you.

Couldn't you use the CRDA database? That's got bits that indicate whether or not some channels allow IBSS in your domain or not.

Thanks.
I think I can use it

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.
