Just tested, seems both ways are needed in order for the NIC port to be SR-IOV enabled in the OS.
Hi, There are two ways to enable SR-IOV in R740/R750 System Setup: System Setup -> System BIOS -> Integrated Devices -> SR-IOV Global Enable System Setup -> Device Settings -> [Choose a NIC port] -> Device Level Configuration -> Virtualization Mode (SR-IOV)   Just wonder if the first way also cover the second (and vice versa) so we don't need to both?
