Given how SRP is structured, I think it's easiest for it to include the service
ID with the PR query. If that makes sense, I can create a patch for it in a
couple of minutes. (SRP is way easier for me to follow than iSER.) I just
can't test SRP.
The only alternative I can think of is for userspace to provide the QoS level
along with the GID, PKey, etc.
