Hi! 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.
