NDIS_STATUS_WAN_LINE_DOWN (Compact 2013)
This status indicates that a WAN-capable miniport driver has lost an established connection with a remote node.
Network Driver Interface Specification (NDIS) 4.x and earlier NDIS WAN miniport drivers use this status indication. NDIS 5.0 through NDIS 6.2 WAN miniport drivers must use the CoNDIS WAN interface.
The StatusBuffer parameter of the NdisMIndicateStatus function contains a pointer to an NDIS_MAC_LINE_DOWN structure. The NdisLinkContext member of NDIS_MAC_LINE_DOWN identifies the link that is no longer valid.
