  vfio is the kernel framework used by the vfio-pci kernel driver.
DPDK drivers do not rely solely on vfio, but rather on vfio-pci to gain
access to pci resources.

Fixes: 0880c40113ef ("drivers: advertise kmod dependencies in pmdinfo")

What would be the impact of not having this fix?
I think it would prevent scripts based on pmd modinfo to load the proper
kernel module (vfio-pci). So I'd suggest to CC stable. What do you think?

Olivier

Mainly reporting an incomplete information on the PMD needs.

Yes, CCing stable sounds sane to me.
