I think I tried that without much success..

How does that work? Have you some other changes in timing here? The log
shows this:

How did it wait almost 11 seconds there between transmitting that test
frame and stopping the test case? Does it really take so long in your
setup to start tshark?

I was able to reproduce this type of pass by adding time.sleep(10)
between that test frame TX and the check_frame_at_gate() calls.. Without
that, the test script is supposed to check the hwsim0.pcapng file
immediately after the test frame has been sent to the wlan2 netdev..

I'm running this with just the single test case. The output looks very
similar to yours if I add that extra 10 second sleep.
