[openib-general] RE: [dat-discussions] round 2 - proposal for socket based connection model

[Kanevsky, Arkady]

It is APIs not ULPs that are concern.
Each ULP can define its own protocol.
But APIs can not.
But defining a protocol for each ULP is also bad.
This proposal defines it for all ULPs.
If ULP uses API, it does the parsing.
If ULP uses verbs it can do the parsing and encoding itself.
But in the later case it will have to have a different ULP
CM for each transport. Bad idea.
