[ovirt-users] Re: tun: unexpected GSO type: 0x0, gso_size 1368, hdr_len 66

hi everyone, With 4.4 I get: ... tun: unexpected GSO type ... It happens to a "third-party" kernel, namely: 5.6.15-1.el8.elrepo.x86_64 on Centos 8.

I wonder if anybody sees the same or similar and I also wonder if I should report it somewhere in Bugzilla as "heads-up" towards new kernels?
