Currently, network dumping failed over a NIC that is a Single Root I/O Virtualization (SR-IOV) virtual device. Usually the driver of the virtual device won't specify the dependency on the driver of the physical device. So to fix this issue, the driver of the physical device needs to be found and installed as well.
