NDIS_PM_WAKE_UP_CAPABILITIES (Windows Embedded CE 6.0)

  • [アーティクル]

1/6/2010

This structure specifies the wake-up capabilities for a NIC. This structure is used by NDIS_PNP_CAPABILITIES.

Syntax

typedef struct _NDIS_PM_WAKE_UP_CAPABILITIES {
  NDIS_DEVICE_POWER_STATE MinMagicPacketWakeUp;
  NDIS_DEVICE_POWER_STATE MinPatternWakeUp;
  NDIS_DEVICE_POWER_STATE MinLinkChangeWakeUp;
} NDIS_PM_WAKE_UP_CAPABILITIES, *PNDIS_PM_WAKE_UP_CAPABILITIES;

Members

  • MinMagicPacketWakeUp
    Specifies the lowest device power state from which the miniport's NIC can signal a wake-up on receipt of a Magic Packet. (A Magic Packet is a packet that contains 16 contiguous copies of the receiving NIC's Ethernet address.)

    The following table shows NDIS_DEVICE_POWER_STATE values defined for device power state.

    Value Description

    NdisDeviceStateUnspecified

    The NIC does not support magic-packet wake-ups.

    NdisDeviceStateD0

    The NIC can signal a magic-packet wake-up from device power state D0. Because D0 is the fully powered state, this does not cause a wake-up but can be used as a runtime event.

    NdisDeviceStateD1

    The NIC can signal a magic-packet wake-up from device power states D1 and D0.

    NdisDeviceStateD2

    The NIC can signal a magic-packet wake-up from device states D2, D1, and D0.

    NdisDeviceStateD3

    The NIC can signal a magic-packet wake-up from device power states D3, D2, D1, and D0.

  • MinPatternWakeUp
    Specifies the lowest device power state from which the miniport's NIC can signal a wake-up event on receipt of a network frame that contains a pattern specified by the protocol driver.

    The following table shows NDIS_DEVICE_POWER_STATE values defined for lowest device power state.

    Value Description

    NdisDeviceStateUnspecified

    The NIC does not support pattern-match wake-ups.

    NdisDeviceStateD0

    The NIC can signal a pattern-match wake-up from device power state D0. Because D0 is the fully powered state, this does not cause a wake-up but can be used as a runtime event.

    NdisDeviceStateD1

    The NIC can signal a pattern-match wake-up from device power states D1 and D0.

    NdisDeviceStateD2

    The NIC can signal a pattern-match wake-up from device power states D2, D1, and D0.

    NdisDeviceStateD3

    The NIC can signal a pattern-match wake-up from device power states D3, D2, D1, and D0.

  • MinLinkChangeWakeUp
    Specifies the lowest device power state from which the miniport's NIC can signal a wake-up event in response to a link change (the connection or disconnection of the NIC's network cable).

    The following table shows the NDIS_DEVICE_POWER_STATE values that signal a wake-up event.

    Value Description

    NdisDeviceStateUnspecified

    The NIC does not support link-change wake-ups.

    NdisDeviceStateD0

    The NIC can signal a link-change wake-up from device power state D0. Because D0 is the fully powered state, this does not cause a wake-up but can be used as a runtime event.

    NdisDeviceStateD1

    The NIC can signal a link-change wake-up from device power states D1 and D0.

    NdisDeviceStateD2

    The NIC can signal a link-change wake-up from device power states D2, D1, and D0.

    NdisDeviceStateD3

    The NIC can signal a link-change wake-up from device power states D3, D2, D1, and D0.

Remarks

If a miniport's NIC does not support a particular wake-up event, the miniport should indicate an NDIS_DEVICE_POWER_STATE of NdisDeviceStateUnspecified for the wake-up event in the NDIS_PM_WAKE_UP_CAPABILITIES structure.

OID_PNP_CAPABILITIES only indicates the wake-up capabilities of a miniport's NIC; it does not enable such capabilities. OID_PNP_ENABLE_WAKE_UP is used to enable a NIC's wake-up capabilities.
