Factory already has version 4.5.1, I'll decide whether backporting the fix to 15.6 makes sense or if we should rather upgrade to 4.5.1 there. -- You are receiving this mail because: You are on the CC list for the bug.

As tcpreplay is not a core part of the system where we should be more careful about version upgrades, I'm going to submit upgrade to version 4.5.1 to Leap 15.6. -- You are receiving this mail because: You are on the CC list for the bug.
