From: Benjamin Berg <benjamin.berg@intel.com>

The comment was referencing the wrong section of the documentation and
was also subtly wrong as it assumed the rules that apply when sending
probe requests directly to a nontransmitted AP. However, in that case
the response comes from the transmitting AP and the AP MLD ID will be
included.
