OID_GEN_LINK_SPEED_EX
As a query, the OID_GEN_LINK_SPEED_EX OID provides the transmit and receive link speeds of an interface.
Version Information
Windows Vista and later
Supported.
NDIS 6.0 and later miniport drivers
Not requested. For NDIS interface providers only.
Remarks
NDIS uses this OID to query the link speed of an NDIS network interface provider. Only NDIS interface providers, and therefore not miniport drivers or filter drivers, must support this OID as an OID request.
This OID returns the link speeds in an NDIS_LINK_SPEED structure.
Miniport drivers supply the link speed during initialization and provide updated link speeds with status indications.
To specify the link speeds in a miniport driver, set the XmitLinkSpeed and RcvLinkSpeed members of the NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure that the miniport driver passes to the NdisMSetMiniportAttributes function.
