Unfortunately, you can't do that.  In fact, the transport system is
designed *not* to pass that type of information all over the place.  And
although a number of use cases for wanting it may be valid, in the
general case it's actually problematic.  There are times, for instance,
when there is no port number as a request may have come in over a
transport that doesn't have one (eg, via AgentX, via the disman
event-mib support, via appletalk, ...).  So we don't generally pass the
transport address that received the information down into the lower
layers because it's not really safe to assume you can get it.
