When sending a TransportMessage via one of the transport prototocols,
addr
contains the destination address,
tprefs
is set to the transport prefences from either the contained EngineMessage,
the NodeIdentityRecord from the Network Identity Store,
or the defaults in the local configuration of the Transport engine,
expiry
is set from the contained EngineMessage,
and msg
contains the message to be sent.
