[DNA] RE: Last Call: 'Link-layer Event Notifications for Detecting NetworkAttachments' to Informational RFC (draft-ietf-dna-link-information)

Sam, you are correct that there the management entities on bridges can
be looked at as hosts that also do bridging. This is however an
exception, and to the best of my understanding the document targets the
general case of attached hosts. To your second point, I am not aware
about operating systems that use bridging and run STP between interfaces
on hosts (again, bridges themselves excluded) but I may not know all.
