Hi,

06/02/2018 00:01, Rohan Gandhi:
> Hello All,
> 
> 1) I am trying to use Mellanox ConnectX-3 to use DPDK on my server
> (Ubuntu 16.04 kernel 4.13.0-32-generic).
> 
> 2) Using dpdk/usertools/dpdk-setup.sh, I can see that the Mellanox

Mellanox drivers do not use neither UIO nor VFIO.


> 3) When I try to use Moongen to use this interface, it returned an
