Hi, Jason
Apparently, your patch should work.
For now, I have an issue where segmentation between two guests on one
host still occurs.
Neither previous "hack" nor your patch helps.
Now I'm looking what the issue may be.
If you have some suggestions on where may I look, it would be helpful, thanks!
I'll check it, thank you!

Hi all,
The issue is that host segments packets between guests on the same host.
Tests show that it happens because SKB_GSO_DODGY skb offload in
virtio_net_hdr_from_skb().
To do segmentation you need to remove SKB_GSO_DODGY or add SKB_GSO_PARTIAL
The solution with DODGY/PARTIAL offload looks like

Added new offloads for TUN devices TUN_F_USO4 and TUN_F_USO6.
Technically they enable NETIF_F_GSO_UDP_L4
(and only if USO4 & USO6 are set simultaneously).
It allows to transmission of large UDP packets.
Different features USO4 and USO6 are required for qemu where Windows guests can
enable disable
