This tasks will involve a bit of troubleshooting.  We need to pinpoint which code change caused tcpdump to break.  One way to do that would be to go back to older images of Haiku, perhaps using the vm images, and do a binary search to find out which version was the last one to work correctly and which one was the first one to show the failure.

Refer to Haiku trac ticket 8839 for more details on the issue.
