Hi Hobywan,
Thanks for the email !
We’ve been working on performance benchmarking. Also, we felt that it would be better to push the driver after Anatoly’s patch (vfio-pci) got in so that we could make the necessary modification before submission.
Now that 1.7.0 is out, we are hopeful of submitting the patch soon.
Thanks,
-Sujith

Hi Sujith,
It was exciting to see open source code coming from Cisco ensuring a DPDK application can run on any platform and with any card....
I haven't seen your patch yet. What happened?
