Hi! This set adds XDP flag for forcing offload and a attachement mode for reporting to user space that program has been offloaded. The nfp driver is modified to make use of the new flags, but also to adhere to the DRV_MODE flag which should disable the HW offload.
Note that the NFP driver currently claims XDP offload support but lacks most basic features like direct packet access.
