I am also curious about the pros and cons of the bifurcated driver compared
with SR-IOV.
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
