Fwd: IW channels list question

Hello iw developers,


I would like to ask a question related to the command iw list. The
channels shown with this command where are they taken from? I mean,
does iw call the drivers' API to see which frequencies it can provide?

I ask this in that if I change the regulatory domain to Japan for
instance, I cannot see the 4.9GHz channels with iw list, does it mean
that the driver doesn't support such a channels or that I maybe have
to modify iw list source in order to make them show up?

Thanks in advance,

REgards,

Francisco
