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

+         Support for L2TP-over-IP socket family.
+
+         The L2TPv3 protocol defines two possible encapsulations for
+         L2TP frames, namely UDP and plain IP (without UDP). This
+         driver provides a new L2TPIP socket family with which
+         userspace L2TPv3 daemons may create L2TP/IP tunnel sockets
+         when UDP encapsulation is not required. When L2TP is carried
+         in IP packets, it used IP protocol number 115, so this port
+         must be enabled in firewalls.
+
+         To compile this driver as a module, choose M here. The module
+         will be called l2tp_ip.
