This is the first foray into upstreaming a vDPA driver for the nfp. Submitting it as RFC initially, since this is touching a new component, not sure if there are potentially any new-to-us requirements this needs to fulfill. We are hoping that this is already in a state to resubmit as PATCH, depending on the feedback this receives.
This series starts out by adding the "enable_vnet" parameter to nfp_devlink, to allow setting the device mode. Next the auxiliary bus driver is added, and the VF probe functions are updated to probe the correct driver, based on the 'enable_vnet' setting. Lastly the nfp_vDPA driver is added, initialising resources and adding callbacks in accordance to the kernel vDPA framework.
