Routine Description:
SonicQueryInformation handles a query operation for a
single OID.
Arguments:
MiniportAdapterContext - Context registered with the wrapper, really
a pointer to the adapter.
Oid - The OID of the query.
InformationBuffer - Holds the result of the query.
InformationBufferLength - The length of InformationBuffer.
BytesWritten - If the call is successful, returns the number
of bytes written to InformationBuffer.
BytesNeeded - If there is not enough room in InformationBuffer
to satisfy the OID, returns the amount of storage needed.
Return Value:
NDIS_STATUS_SUCCESS
