Subject: Re: Possible GRE-TAP/ECT bug

I apologise, I have mistakingly supplied the wrong version.
The lowest kernel version we found this in is v5.3, but this is not a vanilla kernel, but an Ubuntu kernel with probable backports.
Specifically

$ uname -a
Linux ubuntu1910.localdomain 5.3.0-64-generic #58-Ubuntu SMP Fri Jul 10 19:33:51 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

The lowest version from https://kernel.ubuntu.com/~kernel-ppa/mainline/ we found the bug in is v5.7.
i.e. v5.6 does not exhibit the bug, but v5.7 does.
(v5.6.X where X>0 were not checked)
