The following debug mask bits are available:
-PPPOL2TP_MSG_DEBUG verbose debug (if compiled in)
-PPPOL2TP_MSG_CONTROL userspace - kernel interface
-PPPOL2TP_MSG_SEQ sequence numbers handling
-PPPOL2TP_MSG_DATA data packets
+L2TP_MSG_DEBUG verbose debug (if compiled in)
+L2TP_MSG_CONTROL userspace - kernel interface
+L2TP_MSG_SEQ sequence numbers handling
+L2TP_MSG_DATA data packets
If enabled, files under a l2tp debugfs directory can be used to dump
kernel state about L2TP tunnels and sessions. To access it, the
