That's not really related to wireless at all, if you want to do zero-copy IO then you need to checksum when the stuff hits the wire which means out of hardware buffers, which some hardware (including 802.11) doesn't support so you need to copy, nothing wireless specific here :) Anyway, with the changes davem and I are making to actually save the *extra* copy we should be doing well. That's where you want to look for improvements. johannes
