512 is greater that 70. We're only asking for 70 now, so fewer WRs
requested should be "easier" for the driver.
Can you step through the device setup code and make sure that all
the numbers are reasonable? In particular, print out "att" both
before and after the call to ibv_create_qp.
The main difference from the old pvfs version is that now we only
need one QP, not two. Not sure how this could cause the sort of
regression you are seeing (yet).
