	  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.

	  Layer Two Tunneling Protocol Version 3

	  From RFC 3931 <http://www.ietf.org/rfc/rfc3931.txt>.

	  The Layer Two Tunneling Protocol (L2TP) provides a dynamic
	  mechanism for tunneling Layer 2 (L2) "circuits" across a
	  packet-oriented data network (e.g., over IP).  L2TP, as
	  originally defined in RFC 2661, is a standard method for
	  tunneling Point-to-Point Protocol (PPP) [RFC1661] sessions.
	  L2TP has since been adopted for tunneling a number of other
	  L2 protocols, including ATM, Frame Relay, HDLC and even raw
	  ethernet frames.

	  If you are connecting to L2TPv3 equipment, or you want to
	  tunnel raw ethernet frames using L2TP, say Y here. If
	  unsure, say N.
