[IP]: Introduce ip_hdrlen()
For the common sequence "skb->nh.iph->ihl * 4", removing a good number of open coded skb->nh.iph uses, now to go after the rest... Just out of curiosity, here are the idioms found to get the same result: skb->nh.iph->ihl << 2 skb->nh.iph->ihl<<2 skb->nh.iph->ihl * 4 skb->nh.iph->ihl*4 (skb->nh.iph)->ihl * sizeof(u32) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.
