Yup, see my last email.
However this description does not match the implementation. The
implementation is that its a channel if e = 0. My "frequency" is > 1000,
but it was still interpreted as a channel. Looking at the
implementation of iw_float2freq(), the description should be that a
value less than 1e9 is a channel.
So there should really be a check in the user space tools which says
that values between 1000 and 1e9 are invalid. This would catch errors
like the one i made for both 2.4GHz and 5GHz.
