1bee131d52 PPP, L2TP, using LNS chosen destination port 
L2TP LNS might chose its own local port, we actually stored

808098413c PPP: removed PPPoE and PPPoL2TP callback status notifier

74fd2dc9ad PPP: moved ppp_new() to low level protocol init for PPPoE and PPPoL2TP 
First step of a rework of how low level protocols are using the
PPP core. Low level protocols are now going to use the core instead
of core using the low level protocols.

Final goal: separate PPP core code from low level protocols.

44b527415f PPP, slight API change, great code factorisation 
Created new ppp_over_X_create() functions which only prepare the PPP session without starting it

19864a4a08 PPP L2TP, only skip HDLC header if necessary 
RFC 2661 does not specify whether the PPP frame in the L2TP payload should
have a HDLC header or not. We handle both cases for compatibility.

3c122117fc improved PPP API, added ppp_reopen() 
This is now the user choice to re-establish the session in the link status callback
by either calling the ppp_reopen() to re-establish or ppp_delete() to free the PPP
control block. Without user intervention, the PPP control block now stay in the dead
phase, allowing the user to re-establish or delete the control block later.

Sylvain Rochet
bc724ea206 Do not destroy the PPP control block automatically anymore, added ppp_delete() API function. 
Without that, PPP user don't know when and how the PPP control block is free()ed, which
can lead to hard fault.
