I think I want something like this. I would think that dev
should point to the output device by here.
Or should it be skb->dst->dev->mtu?
static inline int ip_send(struct sk_buff *skb)
{
- if (skb->len > skb->dst->pmtu)
+ if ( FRAG_NEXT_HOP ? (skb->len > skb->dev->mtu) : (skb->len > skb->dst->pmtu) )
return ip_fragment(skb, ip_finish_output);
else
return ip_finish_output(skb);
}
