To be called when the authentication (if any) has been completed successfully. If there's no authentication at all, this should be called at the point where the authentication phase would otherwise be.

If the other end has agreed to our request for callback, then this causes NETDIAL to be notified that it's "all systems go" for callback.

If the other end has not confirmed accepted our request for callback, or if we haven't asked, then this does nothing.

Unused

Start the PPP link.

Cleanly stop the LCP link and notify the NIF. If aReason == KErrConnectionTerminated signal Authoritative stop: there is no graceful termination: PPP signals CNifAgentRef::LinkLayerDown to Nifman, which results in PPP deletion.

Open the layer below. Upcall from the FSM.

Signal up event to next layer above Upcall from the FSM.

Received a Config Ack - apply the options Upcall from the FSM.

Modify request after receiving a Config Nak Upcall from the FSM.

Modify request after receiving a Config Reject Upcall from the FSM.

Check if the option list specified matches the original Config-Request option list.

Used for conformance to RFC1661 sections 5.2 and 5.4 (the option list in a Config-Ack or Config-Reject must exactly match the option list in the original Config-Request - same option values in the same order with no new options appended).

Called when the FSM has stopped. Upcall from the FSM.

Construct the Link Protocol Object

Link advisory flow on signal.

Called from the lower layer when it becomes ready.

Called by the link layer for each new PPP packet received. Search registered Recvr list and deliver to all recipients.

Allocates a buffer containing a PPP callback request packet a la draft RFC.

Format is: [ length ] [ type ] [ .. info ... ]

Generate a new magic number, based upon existing number, machine unique ID and tick count.

Notification from Agent

Switch to the next PPP operation phase. When the PPP phase is advanced, protocols may have reached their active phase and so have to be bound in to the main data path and signalled active.

Advance to the next PPP phase after successfully completing the current phase.

Return to a previous PPP operation phase. When the PPP phase is retarded, active protocols may no longer be in their active phase and so have to be unbound from the main data path and signalled inactive.

Called by an upper layer when it is started.

Unload the compression module after a compressed packet is rejected. Upcall from the FSM.

Upcall from binders to send progress

Handle ProvisionConfig messages from SCPR.

Provisioning requirements:

Returns the external IP configuration flag.

Register an object that is interested in receiving certain packets. The receiver object knows the protocol number it is interested in.

Reregister an object that is receiving certain packets. The receiver object knows the protocol number it is interested in.

Retrieve Provisioning Information which becomes available at Flow start time.

Send an LCP Echo Request frame. Called by CPppLrd::TimerComplete periodically

Send an LCP Identification frame (RFC 1570).

Set the MRU

Set the MTU

One of the NCP protocols has been shut down, so kill it. Searches for the registered protocol handler based on the protocol ID.

Cleanly take down the LCP (and therefore PPP) link.

Whether authentication has been completed

Whether CBCP is enabled

Whether we are configured to do Mobile IP

Whether certain extended PPP options from RFC 1570 are to be handled

The reason the link is going down

Authentication protocol object Whether CBCP configuration has been read

The last request received

Whether we are configured for client or server mode

Number of times PppOpen has been called without a corresponding PppClose

Current PPP phase

Authentication protocol framework object

IP Protocol The Compression Control Protocol object

Lower link-layer object

Link quality checking object

List of objects that can receive incoming packets

The action to take once the link goes down
