skb fragmentation
I've seen a couple of drivers (for instance - e100) using fragmented skb on transmit path. I was wondering, how one can do the same on receive ?
Anybody ever tried to do this ? Is there any example of such a driver ?

How? build a fragmented skb on the receive path and send it upwards. Last I looked at the relevant code (2.4.something), however, the tcp/ip stack called skb_linearize() on the skb on its way up, so you wouldn't gain anything unless you teach it to deal with fragmented skb's all the way up. That's just what I recall - this subject was discussed several times in the past, look in the archives for details.
