Hi,

I am working on a new DLEP draft that will be mostly useful in
requesting changes of the radio by the router, similar to the Link
Characteristic Request message type (RFC 8175, Section 12.18).

The issue we see is that the request we are talking about is for the
whole channel, not a special Destination.

RFC 8175 Section 12.18 defines that the referred destination of the
Link Characteristics Request message can be both real (e.g. remote MAC
address) or logical (e.g. multicast group).

Would it be valid to use the "broadcast MAC" to request something for
the whole network or do we need a "Channel/Device Characteristic
Request/Response" message?
