_NDIS_NIC_SWITCH_TYPE enumeration

Description

The NDIS_NIC_SWITCH_TYPE enumeration specifies the type of the NIC switch on a network adapter.

Constants

`NdisNicSwitchTypeUnspecified`

The NIC switch type is not specified.

`NdisNicSwitchTypeExternal`

This value specifies an external switch. The single root I/O virtualization (SR-IOV) virtual ports (VPorts) connected to this type of switch, including the default VPort, can access the external network through the physical port on the network adapter.

`NdisNicSwitchTypeMax`

The maximum value for this enumeration. This value might change in future versions of the NDIS header files and binaries.

Remarks

The SwitchType member of the NDIS_NIC_SWITCH_PARAMETERS and NDIS_NIC_SWITCH_INFO structures is an NDIS_NIC_SWITCH_TYPE enumeration data type.

For more information about the NIC switch, see SR-IOV Architecture.
