Hi Team,

I am trying to use VDPA with ConnectX-6 Dx cards with 5.10 Kernel. Not able to find right documentation for the testing. Please guide me the documentation like how to create and use vdpa devices wtih OVS-kernel.

Thanks in advance.

Hi Team,

Tried following the steps in the ASAP2 offload but VDPA devices are not getting created.  
Getting below error:

# devlink port add pci/0000:b1:00.0 flavour pcisf pfnum 0

kernel answers: Operation not supported

Is there any kernel patches need to take into.
