This patch splits the pppol2tp driver into separate L2TP and PPP parts to prepare for L2TPv3 support. In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

Layer Two Tunneling Protocol
|
|
|
|
From RFC 2661 <http://www.ietf.org/rfc/rfc2661.txt>.
|
|
|
|
L2TP facilitates the tunneling of packets across an
|
|
intervening network in a way that is as transparent as
|
|
possible to both end-users and applications.
|
|
|
|
L2TP is often used to tunnel PPP traffic over IP
|
|
tunnels. One IP tunnel may carry thousands of individual PPP
|
|
connections. L2TP is also used as a VPN protocol, popular
|
|
with home workers to connect to their offices.
|
|
|
|
The kernel component handles only L2TP data packets: a
|
|
userland daemon handles L2TP the control protocol (tunnel
|
|
and session setup). One such daemon is OpenL2TP
|
|
(http://openl2tp.org/).
|
|
|
|
If you don't need L2TP, say N. To compile all L2TP code as
|
|
modules, choose M here.
