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_SIGNALING_ENABLED
We ignore this as of now.
TODO: Add code that uses this and the SIGNALING_DISABLED
OIDs to optimize on making calls.
- OID_CO_SIGNALING_DISABLED
We ignore this for now.
- OID_CO_AF_CLOSE
The Call manager wants us to shut down this AF open .
We ignore all other OIDs.
Arguments:
ProtocolAfContext - Our context for the Address Family binding,
which is a pointer to the ATMEPVC Interface.
ProtocolVcContext - Our context for a VC, which is a pointer to
an ATMEPVC 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
NDIS_STATUS_NOT_RECOGNIZED if we didn't.
