Standard NIC driver module, cxgb4, which runs on base Hypervisor and is responsible for
instantiation and management of the PCIe Virtual Functions (VFs) on the adapter.
•
VF NIC driver module, cxgb4vf, which runs on Virtual Machine (VM) guest OS using VFs
"attached" via Hypervisor VM initiation commands.
