_NET_ADAPTER_LINK_STATE structure

Description

Describes the link state of the adapter.

Members

`Size`

The size of the NET_ADAPTER_LINK_STATE structure, in bytes.

`TxLinkSpeed`

The current transmit link speed of the adapter in bits per second.

`RxLinkSpeed`

The current receive link speed of the adapter in bits per second.

`MediaConnectState`

The media connect state for the network adapter.

`MediaDuplexState`

The media duplex state for the network adapter.

`SupportedPauseFunctions`

Support for the IEEE 802.3 pause frames specified by a NET_ADAPTER_PAUSE_FUNCTION_TYPE value.

`AutoNegotiationFlags`

The auto-negotiation settings for the network adapter. For more info, see NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES.

Remarks

Call NET_ADAPTER_LINK_STATE_INIT or NET_ADAPTER_LINK_STATE_INIT_DISCONNECTED to initialize this structure.

An initialized NET_ADAPTER_LINK_STATE structure is an input parameter value to NetAdapterSetLinkState.
