The PSM library currently implements a static configuration for congestion 
control. The purpose of this patch is to dynamically control the CC configuration
across the fabric with the MADs sent from the FM. The configuration from
the CC related MAD sets are sent up to the PSM library via sysfs reads.

Yes, agreed, the CC agent code is pretty much general and can be moved into 
the IB core. 

Thanks,
