You are too brief. I can come up with one linears based on the API by
myself. I am trying to understand how sharing of SRC between processes
will work and your example doesn't show this. Can I connected the same
SRC to different QPs? If yes, can I send packet to any SRQ connected to
the SRC through any QP connected to the same SRC?  If yes how is this
different from having regular QPs?
