Hi Antonio, Arne, According to the dump, this issue is caused by fragment. If I set link-mtu to 1472 in the condition of encryption "none", it's gone. I also can reproduce the fragment in my Linux x86-64 PC and Linux VM . They use kernel 5.4. Fragment affects the performance in the low-end devices. It also consumes more CPU resource in low-end and high-end devices. If I'm not mistaken, we don't need to set link-mtu without dco. Is this a bug? Can you reproduce? Do I still need to upload my dump? If so, maybe I need to provide a link.
