False alarm... I was using the default tcpreplay binary from Debian instead of the local one :-)
The new version solves the problem, thanks!
from tcpreplay.
Notes:
- The tcpreplay replay + wireshark recording is working if I use the lo (loopback) interface, so this is a tap-specific problem.
- I have the same problem with the latest tcpreplay version (4.4.4) compiled from sources (the ./configure phase shows: "Tuntap device support: yes").
- After reading #411 I tried to use another name for the tap interface (not starting with "tap"), but same problem.
Thank you for your help.

I used git bisect and found the culprit:

Hi @fklassen. I've tested branch 4.5.0-beta1 and the problem seems to be still here.
