GUID_NDIS_STATUS_LINK_STATE
The GUID_NDIS_STATUS_LINK_STATE event GUID indicates that there has been a change in the link state of a miniport adapter. This WMI GUID is supported in NDIS 6.0 and later versions.
Miniport drivers use the NDIS_STATUS_LINK_STATE status indication to notify NDIS and overlying drivers that there has been a change in link state.
When a miniport driver indicates a link state change, NDIS translates the status indication to a WMI GUID_NDIS_STATUS_LINK_STATE event for WMI clients.
The data buffer that NDIS provides with the GUID contains an NDIS_WMI_EVENT_HEADER structure that is followed by an NDIS_LINK_STATE structure. The NDIS_LINK_STATE structure specifies the physical state of the medium.
