Hi Rami,

I found the switch for testpmd to use a cmd line script instead = of using interactive mode. Still need to see if loading a ddp persists = on the card when rebinding the i40e driver instead of vfio / = uio.

The kernel i40e driver also seems to have the functions to use = AdminQ to load DDPs onto the card =E2=80=93 however im not sure how to = do it from userland.

Hi = Sebastian,

I don't know of = such a way, unfortunately. Also you cannot automate = testpmd

as it is to load = the profile automatically without going interactive = mode.
