I really disalike pull requests of this form. You add lots of datastructures and helper functions but no actual users of these facilities to the driver.
Do this instead:
1) Add TSAR infrastructure
2) Add use of TSAR facilities to the driver
That's one pull request.
I don't care if this is hard, or if there are entanglements with
Infiniband or whatever, you must submit changes in this manner.
I will not accept additions to a driver that don't even get really
used.
