[openib-general] RE: [dat-discussions] socket based connection model for IB proposal - round 3

[Sean Hefty]

If you want to maximize consumer usable private data, then you can move the 
version, IP version, protocol, source and destination ports into the service ID.

Separately, if there's any defined mapping to a service ID or set of service 
IDs, then the service ID indicates the format of the private data.  No 
additional information is needed in the CM REQ, such as using a reserve bit.

To be clear, the CM REQ _carries_ the IP address.  There should be no 
requirement that the CM performs the mapping, and I see no reason why it should 
even care.
