  Using libsdp with netperf shows some of the limitations of libsdp.
netperf connects to the server on a well known socket, but then the
server creates a second socket which it autobinds, checks to see
which port was assigned, and passes the port number to the client
which connects to the port. This second connection is then used for
the data transfer. 

  Since the connection is not on a well known port the way to match
it is with the 'program' keyword:

  match program netperf

  The socket size socket option is still in the TODO file.
