case __constant_htons(ETH_P_IP):
{
struct iphdr *iph = skb->nh.iph;
h = iph->daddr;
h2 = iph->saddr^iph->protocol;
if (!(iph->frag_off&htons(IP_MF|IP_OFFSET)) &&
(iph->protocol == IPPROTO_TCP ||
iph->protocol == IPPROTO_UDP ||
iph->protocol == IPPROTO_ESP))
h2 ^= *(((u32*)iph) + iph->ihl);
break;
}
In case of ipv4:
destination address
source address
ip protocol
source port/dest port tuple
I missed the fact that the first 4 octects of the IP sub-protocol header
were include in (u32).

Read the HOWTO. Scp doesn't set the 'minimum delay' flag.
