or does it have some other advantage over the umad layer (from Hal's
response seems like umad has better layering/functionality) ?

If that is the case than you can also suggest to replace the OpenIB
verbs layer or CM, etc' with the IBAL one because its present in Windows


I believe if we want to do a major change in the management
infrastructure that is live and kicking (can probably improve like
always) 
We need a much better reason than "its done this way in Windows"
