Jason,
With Mellanox writing and fixing the vast majority of the code found
in IB/IPoIB, do you or one of your colleagues want to look into this?
It would be considerably less error-prone if the authors of that code
did that more risky work of backporting.
AFAIK, Mellanox also has the regression tests to ensure that everything
still works after this re-write as it did before.
Thanks,
Gerd
