====================
nfp: protect from theoretical size overflows and SR-IOV errors

This small set changes the handling of pci_sriov_set_totalvfs() errors.
nfp is the only driver which fails probe on pci_sriov_set_totalvfs()
errors.  It turns out some BIOS configurations may break SR-IOV and
users who don't use that feature should not suffer.

Remaining patches makes sure we use overflow-safe function for ring
allocation, even though ring sizes are limited.  It won't hurt and
we can also enable fallback to vmalloc() if memory is tight while
at it.
