This does not apply to the 5.15.y tree at all, due to:

...

• inet_proto_csum_replace_by_diff(ptr, skb, to, is_pseudo, false);
  

• inet_proto_csum_replace_by_diff(ptr, skb, to, is_pseudo, is_ipv6);
  

This chunk.

Can you fix that up and resend just this one?

It requires the 1/2 patch to apply correctly. I've tested them on the tip of 5.15.y (1c700860e8bc). Or is there some reason not to backport the 1/2 patch?
