[nginx-quic] Segmentation offloading

I was testing this feature the other day but unsure if it's doing the right
Nginx is generating 65k UDP datagrams which are then being fragmented at
the IP layer.
Reading the spec, rfc9000, it looks like IP fragmentation is not allowed
"UDP datagrams MUST NOT be fragmented at the IP layer. In IPv4
IPv4 <https://datatracker.ietf.org/doc/html/rfc9000#ref-IPv4>], the
Don't Fragment (DF) bit MUST be set if possible, to
prevent fragmentation on the path."
Also, it doesn't seem to be respecting the client's endpoint
Can you please confirm if this is desired ?
