Calls to MiniportSetInformation changes information maintained by the miniport. This function definition and operation is the same as in a LAN miniport NIC driver except that certain WAN-specific OIDs must be recognized.
No other requests will be submitted to the WAN driver until the current set request is complete. If the WAN driver does not complete the call immediately (by returning NDIS_STATUS_PENDING), it must call NdisMSetInformationComplete to complete the call.
Any of the settable NDIS global OIDs can be used, although a WAN miniport cannot set the NDIS_MAC_OPTION_FULL_DUPLEX flag in response to an OID_GEN_MAC_OPTIONS request. The following WAN-specific OID is passed to MiniportSetInformation.
This OID is used to set the link characteristics. The parameters in the structure passed for this OID are described previously for OID_WAN_GET_LINK_INFO.
