Maybe skb_header_pointer() is lighter.
A little worse than skb_copy_bits(). In any case, this change is going to hurt. Dave, can we assume the upper layers(qdiscs in this case) are responsible for any linearizing? Changli, if you have time - can you also audit tcf_pedit() since it follows TheLinuxWay(tm). cheers, jamal
