== About This Document ==
**[[LAN Adapter and Protocol Support - IBM Product Overview]]
This document proposes extensions to the current Network Driver Interface Specification (NDIS) 2.0.1 dated October 5, 1990. These extensions are required in order for IBM* to properly implement the IEEE 802.2 CCB interface as an NDIS protocol driver. These extensions would not necessarily require a change to existing media access control (MAC) device drivers. In fact, these extensions are intended only for 802.5 type MAC device drivers. A MAC device driver can indicate that the extensions in this document are supported by setting the minor NDIS version to 02 in the common characteristics table.
**[[IBM OS/2 LAN Server 3.0 Product Overview]]
 
**[[IBM Network Transport Services/2 Version 1.0 Product Overview]]
The proposal would add a new primitive to the NDIS interface and also extend the MAC service specific characteristics table (SSC) and the MAC media specific statistics (MSS) for 802.5 Details of these extensions are given in the following sections.

'''Note:''' NDIS 2.0.1 is jointly authored by 3Com** and Microsoft.** The SSC and MSS are tables defined in the NDIS. The extensions to NDIS 2.0.1, as described in this document, are derived by IBM.

          0x00FF      GENERAL_FAILURE</pre>
Description:
 
This command directs a MAC device driver to change the adapter specific OpenOptions on the adapter. For IBM Token-Ring compatible adapters, OpenOptions are defined in the ''IBM LAN Technical Reference Manual.''
 
=== 1.2 Change to Service Flags to Support ModifyOpenParms ===
Bit 17 of the Service flags in the MAC device driver SCC indicates if the MAC device driver supports the modification of the Open parameters with the new ModifyOpenParms NDIS primitive.
 
== 2.0 Proposed Changes to the MAC SSC ==
The MAC SSC will be extended to include a pointer to a new table.
 
'''Note:''' The pointer to this new table is included immediately following the Max number of data blocks in the current definition of the MAC SSC.
 
This new table has the following structure:
<pre>        BYTE            AdapterConfig (DIR. STATUS)
        BYTE            Reserved
        BYTE(10)        MicroCodeLevel (DIR.STATUS)
        DWORD          AdapterParmsAddr (DIR.STATUS)
        DWORD          AdapterMACAddr (DIR. STATUS)
        WORD            SRAMAddress (DIR. INITIALIZE)
        WORD            BringUps (DIR. INITIALIZE and DIR.OPEN.ADAPTER)
        WORD            AdapterType (DIR. STATUS)</pre>
The previous values are needed to support the IBM IEEE 802.2 CCB interface DIR.STATUS and DIR.INITIALIZE commands. These commands are defined in the ''IBM LAN Technical Reference'' as follows:
{|
|width="50%"|'''Previous Value'''
|width="50%"|'''New Value and Location'''
|-
|AdapterConfig
|adapter_config in DIR.STATUS
|-
|MicroCodeLevel
|microcode_level in DIR.STATUS
|-
|AdapterParmAddr
|adapter_parms_addr in DIR.STATUS
|-
|AdapterMACAddr
|adapter_mac_addr in DIR.STATUS
|-
|SRAMAddress
|SRAM_address in DIR.INITIALIZE
|-
|BringUps
|bring_ups in DIR.INTIALIZE and DIR.OPEN.ADAPTER
|-
|AdapterType
|adapter_type in DIR.STATUS
|}
 
Note that a protocol can determine if the MAC device driver supports this extended table format by looking at the minor NDIS version byte of the common characteristics table. This byte is set to 02 for this version. A MAC device driver may not need to support the extended SSC format but needs to support version 2.02 for some other reason (for example ModifyOpenParms). This can be done by setting the minor NDIS version byte of the CCT to 02 and setting the pointer to the previously defined structure to NULL.
 
Also note that even though link speed is already returned in the common characteristics table, it should also be returned in the AdapterConfig byte.
 
Certain adapter cards may not be able to support all of the fields in this structure. For these MAC device drivers, binary 0's can be inserted in those fields that are not supported.
 
== 3.0 Proposed Changes to the MAC 802.5 Media Specific Statistics ==
The MAC media specific statistics (MSS) are extended to include the following information:
 
<pre class="western">    WORD        RingUtilizationMeasurement (DIR.STATUS)</pre>
'''Note''': The fields defined here are included immediately following the number of underruns in the current definition of the MAC MSS.
 
The previous value is needed in order to support the IBM IEEE 802.2 CCB interface DIR.STATUS. It is defined in the ''IBM LAN Technical Reference'' as follows:
 
<pre class="western">RingUtilizationMeasurement is ring utilization measurement in (DIR.STATUS)</pre>
Note that a protocol can determine if the MAC device driver supports this extended table format by looking at the minor NDIS version byte of the common characteristics table. This byte is set to 02 for this version. 'The 802.5 statistics structure version level is also 02 in the 802.5 MSS.
 
Note that if this counter is not supported, it must be set to FFFF.
 
== 4.0 Proposed Changes to the Status Indication General Request ==
An additional Status Indication is being proposed to inform the upper layers of status changes concerning the presence of the PCMCIA LAN adapters. Existing protocol stacks that do not support this new NDIS primitive will have to rely on existing NDIS support for error indications. For situations where the new Status Indication is not supported the existing Ring Status Status Indication of Lobe Wire Fault would be appropriate. The Status Indication is called AdapterPresence.
 
<pre class="western">Purpose: Return a change in the Presence of a LAN Adapter.
 
PUSH WORD      MACID          ;Module ID of MAC
PUSH WORD      Status          ;New Adapter Status
PUSH LPBYTE    Indicate        ;Virtual address if indicate flag
PUSH WORD      6              ;Adapter Presences Indication
PUSH WORD      ProtDS          ;DS of called protocol module
Call Status           
 
Returns:
                0x0000  SUCCESS</pre>
Called by LAN MAC drivers to indicate a change in the presence of a LAN Adapter. The status codes for the MAC drivers are encoded in a 16 bit mask, where the bits for the mask are defined as:
 
{|
|width="50%"|'''Bit'''
|width="50%"|'''Meaning'''
|-
|15
|Ejection Request
|-
|14
|Ejection Complete
|-
|13
|Insertion Request
|-
|12
|Insertion Complete
|-
|11
|Card Insertion
|-
|10
|Card Removal
|-
|9
|PM Resume(Reserved)
|-
|8
|PM Suspend (Reserved)
|-
|7-0
|Reserved
|}
 
For further details refer to the PCMCIA Card Services Interface Specification, Release 2.00 and Network Driver Interface Specification, Version 2.01.
 
'''Note:''' Currently, only the NetBEUI device driver supports these proposed extensions. This implementation in NetBEUI only supports the Card Insertion and Card Removal status codes. The Card Removal status code is reported as a Lobe Wire Fault to the application.
