This Kconfig help text is a little weak. Why not include the text
you've already written here:
Support Alternative Routing-ID Interpretation (ARI), which
increases the number of functions that can be supported by a PCIe
endpoint. ARI is required by SR-IOV.
In the Kconfig text, you might want to expand the SR-IOV acronym
too.
Thanks.
