That file is correct.

About the only enhancements you *might* want to consider would be to calculate
what the CRC would have been for the delimiter and put it into the radiotap
header, but that's not required.

Note also that you're setting the "FCS present" flag in the radiotap Flags
field, but there doesn't appear to be a valid FCS value at the end of the frame
- it's all zeroes.

If you had to change the code in ns3 itself, please submit your changes to the
ns3 developers as part of a bug report.

If you had to change your own code implemented atop ns3, then, other than the
two possible CRC-related enhancements I mentioned, you're done.
