I'm looking the best value of max_vfs on SR-IOV configuration of virtualization host. I find following statement on ConnectX-5 EN brochure.
SR-IOV: Up to 1K Virtual Functions
SR-IOV: Up to 16 Physical Functions per host
Let's say that the virtualization host is equipped with total of 40 cores (80 threads). Should I use 1024 or 64 (1024/16) for max_vfs? If not, what is the optimal one for that environment? How to utilize all ConnectX-5 EN VF? How to utilize all ConnectX-5 EN PF?
