I know squat about skb, but I managed to hack the rshaper
driver to look only at TCP packets. The code (for v2.2.x)
looks like this:
struct iphdr *ih = (struct iphdr *)(skb->data);
if (ih->protocol == IPPROTO_TCP) {
u32 saddr = ih->saddr;
u32 daddr = ih->daddr;
That (struct iphdr *) cast looks pretty suspect, but it does
work. (Maybe only because all my LAN traffic is IP?)
