[ns] Using "bytes_" in SatPEP Sink

Hello all,

I'm trying to use the SatPEP contribution to NS, but when I try to simulate
a simple topology :

<-------TCPNewreno-------->[Sink0|Send0]<-------TCPWestwood--------->[Sink1|Send1]<----------TCPNewreno------------->

I observe that the "bytes_" variable of Sink1 is always null. Sink0 receives
bytes_, sends them to Send0 via "sendmsg" function, but in practice it seems
that between Send0 and Sink1 no bytes are exchange. So, there is a problem
with the split connection, and I wanted to know if you have already worked
with SatPEP and experienced this problem when trying to monitor the "bytes_"
variable of the TCP Split Sink.

Thanks,

Julien.
