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.
L2TPv3 allows other protocols as well as PPP to be carried
over L2TP tunnels. L2TPv3 is defined in RFC 3931
<http://www.ietf.org/rfc/rfc3931.txt>.
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.
