_NDIS_NIC_SWITCH_VPORT_INTERRUPT_MODERATION enumeration

Description

The NDIS_NIC_SWITCH_VPORT_INTERRUPT_MODERATION enumeration specifies the interrupt moderation setting of a single root I/O virtualization (SR-IOV) virtual port (VPort) on the NIC switch.

Constants

`NdisNicSwitchVPortInterruptModerationUndefined`

Interrupt moderation for the VPort is not defined.

`NdisNicSwitchVPortInterruptModerationAdaptive`

Interrupt moderation for the VPort is adaptive. This state enables the network adapter to adjust the interrupt moderation rate for the VPort based on the pattern of network traffic.

`NdisNicSwitchVPortInterruptModerationOff`

Interrupt moderation for the VPort is disabled.

`NdisNicSwitchVPortInterruptModerationLow`

Interrupt moderation for the VPort is low.

`NdisNicSwitchVPortInterruptModerationMedium`

Interrupt moderation for the VPort is medium.

`NdisNicSwitchVPortInterruptModerationHigh`

Interrupt moderation for the VPort is high.

Remarks

The determination of low, medium, and high interrupt moderation levels is determined by the miniport driver based on a hardware algorithm that is based on the network adapter.

The InterruptModeration member of the NDIS_NIC_SWITCH_VPORT_PARAMETERS and NDIS_NIC_SWITCH_VPORT_INFO structures is an NDIS_NIC_SWITCH_VPORT_INTERRUPT_MODERATION enumeration data type.
