Added "provision for rewound PPP frames" that allows receiving

reorder packets to pass to the upper layer without reorder.  It
will improve performance (throughput or loss rate) for PPTP or
L2TP(/IPesc) on networks that latency is unstable such as mobile
network.

As our test environment (bandwidth: 6Mbps, latency: 50ms for 97% of
traffic and 52ms for rest of traffic), throughput has changed from
0.76MB to 2.17MB on file upload by PPTP connected Windows Vista
ftp.exe.

Developed by UMEZAWA Takeshi at IIJ.
