Also print the frequencies in MHz in the "get_capability channels" command and
add a tag "NO_IBSS" if IBSS mode is not allowed on a channel.

This control interface command may already be used by external programs
and changing the format of the returned information could result in
compatibility issues. As such, I don't think this is acceptable without
introducing a different way of fetching this new format (e.g.,
"get_capability freq").
