To be precise, 0x7e is escaped in PPP in HDLC-like framing.  However, at
least as I read the L2TP spec, the framing is supposed to be removed by
the time the packets are encapsulated in L2TP, so that a 0x7e is just a
0x7e.
On the other hand if we are removing the escaping as 2661 seems to suggest then would calling the ppp_hdlc dissector on the L2TP's PPP payload work?
