This section describes the requirements and guidelines for managing the NIC switch of a network adapter that supports single root I/O virtualization (SR-IOV). The miniport driver for the PCI Express (PCIe) Physical Function (PF) of the SR-IOV network adapter manages the NIC switch on the adapter.
This section includes the following topics:
Enumerating NIC Switches on a Network Adapter
Querying the Parameters of a NIC Switch
Setting the Parameters of a NIC Switch
For more information on NIC switches for SR-IOV network adapters, see NIC Switches.
Note Only the PF miniport driver can configure the network adapter's hardware resources, such as the NIC switch. The miniport driver for a PCIe Virtual Function (VF) on the SR-IOV network adapter cannot directly access most of the adapter's hardware resources. For more information, see Writing SR-IOV VF Miniport Drivers.
