Routine Description:
|
||
|
|
|
||
|
|
This routine is called by NDIS when our Call Manager sends us an
|
||
|
|
NDIS Request. NDIS Requests that are of significance to us are:
|
||
|
|
- OID_CO_ADDRESS_CHANGE
|
||
|
|
The set of addresses registered with the switch has changed,
|
||
|
|
i.e. address registration is complete. We issue an NDIS Request
|
||
|
|
ourselves to get the list of addresses registered.
|
||
|
|
- OID_CO_AF_CLOSE
|
||
|
|
The Call Manager wants us to shut down this Interface.
|
||
|
|
|
||
|
|
We ignore all other OIDs.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
ProtocolAfContext - Our context for the Address Family binding,
|
||
|
|
which is a pointer to the ATMSM Interface.
|
||
|
|
ProtocolVcContext - Our context for a VC, which is a pointer to
|
||
|
|
an ATMSM VC structure.
|
||
|
|
ProtocolPartyContext - Our context for a Party. Since we don't do
|
||
|
|
PMP, this is ignored (must be NULL).
|
||
|
|
pNdisRequest - Pointer to the NDIS Request.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
NDIS_STATUS_SUCCESS if we recognized the OID

Routine Description:
|

|
|

|
|
This routine is called by NDIS when a previous call to NdisCoRequest
|

|
that had pended, is complete. We handle this based on the request
|
||
|
|
we had sent, which has to be one of:
|
||
|
|
- OID_CO_GET_ADDRESSES
|
||
|
|
Get all addresses registered on the specified AF binding.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
Status - Status of the Request.
|
||
|
|
ProtocolAfContext - Our context for the Address Family binding,
|
||
|
|
which is a pointer to the PATMSM_ADAPTER.
|
||
|
|
ProtocolVcContext - Our context for a VC, which is a pointer to
|
||
|
|
a VC structure.

|
ProtocolPartyContext - Our context for a Party
|
