I understand the possible collision, but i don't measure well the real impact in the source code. Hping3 author is not active anymore on this project and i can only maintain the packaging or minor modifications, so unless there is a blocker issue, i'll not investigate the problem further (but another patch for hping3 could be integrated in Debian if someone want to take the time).
