[openib-general] Performance Degradation with OFED v. Voltaire(lustre)

[Bernadat, Philippe]

Koren & Or,

I am building and testing as we speak.
But my feeling is that this issue shouldn't require user to set the
tavor_quirk param.

The stack should detect this HCA flavor at the appropriate end (active
according to Or) and should automatically adjust the MTU.
