[ofa-general] [PATCH 3/4] rdma/cm: add ability to specify typeof service

Adding the SID to the PR query is easy enough to do.  Here's the issue 
that I would like to resolve first.

Starting first with something transport neutral, I propose the using 
rdma_set_service_type() combined with the flowinfo in the IPv6 address. 
  If we can agree that this is usable, now let's add the SID to the PR 
query.

Since, SID -> QoS, and rdma_set_service_type() sets the QoS, what gets 
set in the PR query?  The SID -> QoS may not match the QoS requested by 
the application.  Should the SID always be set, or only if QoS is not 
specified through some other means?
