What are the practical differences between running a bifurcated driver vs. running SR-IOV mode where the kernel owns the PF and userspace applications own the VFs? Specifically, could I run the ixgbe driver in the kernel (max_vfs=N), control it via ethtool, and then access the queues via userspace VF drivers? If so, how would this differ from the bifurcated driver? Cheers, -Luke
