[openib-general] Infiniband Subnet Management

[Eitan Zahavi]

Hi Adit,

IB QoS work on OpenFabrics is planned to happen for the 1.2 release 
(hopefully I did not miss-named it).
Regarding which OpenSM is better for that respect :

osmsh
    - was a full blown CLI for OpenSM
    - unfortunately is not supported anymore by this community
    - probably due a lack of  demand.

Current OpenSM (OFED 1.1, OFA trunk)
    - provide a way for you to set a uniform SL2VL and VLArb tables (one 
for each device type - CA/Router/Switch)

New OpenSM (under devel)
   - better control via policy file
