Looks like ocrdma will break here.
I'm not sure about mthca.
qib, mlx4 are fine. mlx5 should be as well I would think (I don't have that
hardware.)
hfi1 did not process these MADs previously as all the hardware counters are 64
bits. But with this patch series we would add it.
ehca, amso1100, and ipath are all gone so they don't matter.
I can whip up a patch for hfi1 and we have to wait for Doug to take over that
driver anyway to make sure that the patch would apply. So I think you can
ignore it.
ocrdma seems like it could be a quick patch pre this one.
