NDIS_NIC_SWITCH_VPORT_STATE enumeration (ntddndis.h)

  • Article

The NDIS_NIC_SWITCH_VPORT_STATE enumeration specifies the state of a single root I/O virtualization (SR-IOV) virtual port (VPort) on the NIC switch of a network adapter.

Syntax

typedef enum _NDIS_NIC_SWITCH_VPORT_STATE {
  NdisNicSwitchVPortStateUndefined,
  NdisNicSwitchVPortStateActivated,
  NdisNicSwitchVPortStateDeactivated,
  NdisNicSwitchVPortStateMaximum
} NDIS_NIC_SWITCH_VPORT_STATE, *PNDIS_NIC_SWITCH_VPORT_STATE;

Constants

 
NdisNicSwitchVPortStateUndefined
The VPort state is not defined.
NdisNicSwitchVPortStateActivated
The VPort is allocated and in an activated state.

Note  The default VPort attached to the PCI Express (PCIe) Physical Function (PF) and nondefault VPorts attached to PCIe Virtual Functions (VFs) are created in an activated state. Once created, these VPorts cannot be deactivated.

 
NdisNicSwitchVPortStateDeactivated
The VPort is allocated and in a deactivated state.

Note  Nondefault VPorts attached to the PF are created in a deactivated state. These VPorts can be activated by using OID set requests of OID_NIC_SWITCH_VPORT_PARAMETERS. However, once activated, these VPorts cannot be deactivated.

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

Remarks

The VPortState member of the NDIS_NIC_SWITCH_VPORT_PARAMETERS and NDIS_NIC_SWITCH_VPORT_INFO structures is an NDIS_NIC_SWITCH_VPORT_STATE enumeration data type.
