I believe the issue (not certain - need more test time) was caused by not specifying all vlarb entries,
even those unused. So, QoS on, but incomplete specification. OFED HowTo examples do this, so I figured it
was OK.

Its also possible that some software may have been specifying an un-configured SL - without my permission ;)
Maybe vl 0 was loosing its turn in arbitration and got starved for > +3%/-51% 400,000 symbols when the HCA
was passing back flow control update?

Unfortunately - it usually worked, except under load.

Think its working now.
