typedef struct _NDIS_MAC_LINE_DOWN { IN NDIS_HANDLE NdisLinkContext; } NDIS_MAC_LINE_DOWN, *PNDIS_MAC_LINE_DOWN;
NDIS_MAC_LINE_DOWN contains information associated with a line-down indication made by a WAN NIC miniport.
A WAN NIC driver calls NdisMIndicateStatus with this type of indication when a link between a local node and a remote node in a wide area network becomes inactive.
NDISWAN forwards such a line-down indication to the affected protocol(s), formatted as an NDIS_WAN_LINE_DOWN structure.
