As a quick update, since yesterday I have confirmed that several
different microarchitecture implementations (different PCIe) have tested
and validated this patch series. Those minimally include:

* Cavium Networks ThunderX
* Qualcomm Technologies Inc QDF2XXX
* AMD A1100 ("Seattle")

Another is working on testing over the weekend. Still waiting for an ARM
tested-by on Juno I think. I will personally be testing this and future
releases on all of the above mentioned hw.

Jon.
