Hi Florian
214 static int ip_finish_output_gso(struct sk_buff *skb)
215 {
216 netdev_features_t features;
217 struct sk_buff *segs;
218 int ret = 0;
219
220 /* common case: locally created skb or seglen is <= mtu */
221 if (((IPCB(skb)->flags & IPSKB_FORWARDED) == 0) ||
222 skb_gso_network_seglen(skb) <= ip_skb_dst_mtu(skb))
223 return ip_finish_output2(skb);
Could you please state _concrete_ _reason_ why locally created skb length is
＿always＿ fitting into MTU size?
Especially in below scenario:

As many people have discuss it in this thread:
