Currently, when adding the 6 GHz Band Capabilities element, the channel
list of the wiphy is checked to determine if 6 GHz is supported for a given
virtual interface. However, in a multi-radio wiphy (e.g., one that has
both lower bands and 6 GHz combined), the wiphy advertises support for
all bands. As a result, the 6 GHz Band Capabilities element is incorrectly
included in mesh beacon and station's association request frames of
interfaces operating in lower bands, without verifying whether the
interface is actually operating in a 6 GHz channel.
This is not incorrect.
While this might be appropriate for a multi-band wiphy (i.e., a single
radio capable of operating on both 5 GHz and 6 GHz), it may not be
suitable for a multi-radio wiphy where each band is handled by a
separate radio. In such cases, the Mesh BSS could be running on the 5
GHz radio, which does not inherently support 6 GHz capabilities.
Should we change this specific to multi-radio wiphy ?
