           Summary: Loss of Tag and change in size of Packet using TCP.
           Product: ns-3
           Version: pre-release
          Platform: All
        OS/Version: Linux
            Status: NEW
          Keywords: bug
          Severity: normal
          Priority: P3
         Component: internet-node
        AssignedTo: ns-bugs at isi.edu

I have a Packet that I send using a point-to-point TCP connection. I am seeing
an attached Tag disappear on the receiving side and the size changes. I think
these both may be bugs. I'll attach a test case below. 

I've used the component of internet-node, but thats just a wild guess.

Compile---%<-------------------%<----------%<----------%<----------%<---------%<

note, that the size changes from 536->535 and the tag is gone.

Thanks,
