Spoke and Mesh SDPs

When an SDP is bound to a service, it is bound as either a spoke SDP or a mesh SDP. The type of

SDP indicates how flooded traffic is transmitted.

A spoke SDP is treated like the equivalent of a traditional bridge "port" where flooded traffic

received on the spoke SDP is replicated on all other "ports" (other spoke and mesh SDPs or SAPs)

and not transmitted on the port it was received.

All mesh SDPs bound to a service are logically treated like a single bridge "port" for flooded

traffic where flooded traffic received on any mesh SDP on the service is replicated to other "ports"

(spoke SDPs and SAPs) and not transmitted on any mesh SDPs.
