- MediumArray Array of ndis media passed down to us to pick from
- MediumArraySize Size of the array
- MiniportAdapterHandle The handle NDIS uses to refer to us

-Routine Description:
-
- Entry point called by NDIS to query for the value of the specified OID.
- Typical processing is to forward the query down to the underlying miniport.
-
- The following OIDs are filtered here:
-
- OID_PNP_QUERY_POWER - return success right here
-
- OID_GEN_SUPPORTED_GUIDS - do not forward, otherwise we will show up
- multiple instances of private GUIDs supported by the underlying miniport.
-
- OID_PNP_CAPABILITIES - we do send this down to the lower miniport, but
- the values returned are postprocessed before we complete this request;
- see PtRequestComplete.
-
- NOTE on OID_TCP_TASK_OFFLOAD - if this IM driver modifies the contents
- of data it passes through such that a lower miniport may not be able
- to perform TCP task offload, then it should not forward this OID down,
- but fail it here with the status NDIS_STATUS_NOT_SUPPORTED. This is to
- avoid performing incorrect transformations on data.
-
- If our miniport edge (upper edge) is at a low-power state, fail the request.
-
- If our protocol edge (lower edge) has been notified of a low-power state,
- we pend this request until the miniport below has been set to D0. Since
- requests to miniports are serialized always, at most a single request will
- be pended.
-
-Arguments:
-
- MiniportAdapterContext Pointer to the adapter structure
- Oid Oid for this query
- InformationBuffer Buffer for information
- InformationBufferLength Size of this buffer
- BytesWritten Specifies how much info is written

- OID_PNP_CAPABILITIES - we do send this down to the lower miniport, but\r
- the values returned are postprocessed before we complete this request;\r
- see PtRequestComplete.\r
-\r
- NOTE on OID_TCP_TASK_OFFLOAD - if this IM driver modifies the contents\r
- of data it passes through such that a lower miniport may not be able\r
- to perform TCP task offload, then it should not forward this OID down,\r
- but fail it here with the status NDIS_STATUS_NOT_SUPPORTED. This is to\r
- avoid performing incorrect transformations on data.\r
-\r
- If our miniport edge (upper edge) is at a low-power state, fail the request.\r
-\r
- If our protocol edge (lower edge) has been notified of a low-power state,\r
- we pend this request until the miniport below has been set to D0. Since\r
- requests to miniports are serialized always, at most a single request will\r
- be pended.\r

-; Notes:\r
-; 0. The term "filter" is used in this INF to refer to an NDIS IM driver that\r

-; Since Windows 2000 systems do not have support for CopyINF directive,\r

-sample is a do-nothing pass-through NDIS 5 driver that demonstrates the basic\r
-principles underlying an NDIS Intermediate Miniport (IM) driver. This driver\r
-exposes a virtual adapter for each binding to a real or virtual NDIS adapter.\r
-Protocols bind to these virtual adapters as if they are real adapters. <o:p></o:p></span></p>\r
-\r
-<p><span style='font-size:10.0pt;font-family:Verdana'>The <span class=SpellE>Passthru</span>\r
-driver re-packages and sends down all requests and sends submitted to this\r
-virtual adapter. The <span class=SpellE>Passthru</span> driver can be modified\r
-to change the data before passing it along. For example, it could\r
-encrypt/compress outgoing and decrypt/decompress incoming data.<o:p></o:p></span></p>\r

-<p><span class=SpellE><span style='font-size:10.0pt;font-family:Verdana'>Passthru</span></span><span\r

-Routine Description:\r
-\r
- This is a notification to our protocol edge of the power state\r
- of the lower miniport. If it is going to a low-power state, we must\r
- wait here for all outstanding sends and requests to complete.\r
-\r
- NDIS 5.1: Since we use packet stacking, it is not sufficient to\r
- check usage of our local send packet pool to detect whether or not\r
- all outstanding sends have completed. For this, use the new API\r
- NdisQueryPendingIOCount.\r
-\r
- NDIS 5.1: Use the 5.1 API NdisIMNotifyPnPEvent to pass on PnP\r
- notifications to upper protocol(s).\r

- pNetPnPEvent - The Net Pnp Event. this contains the new device state\r
