Update:
- It fails after ~240...253 packages. After that, no ping response is received any more
- I use "sudo ./oob-net-ping -i enp7s0 -a 192.168.122.1 -w 1000" so it fails faster
- Also without -w 1000, it fails, you just have to wait longer
- With an I350 card, I get the kernel WARNING
- In a VM with an e1000e, I don't get a warning but still after ~250 packages, no response is
received any more
- After evl net -di / evl net -ei, it works for another ~250 packages until it fails again
- With the good version, I tested ~1M packages, all fine, max 60 us response time on the real PC
