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
Actually the main protocols (TCP,UDP,RAW) work with fragmented skbs. The skb_linearize() users are mostly netfilter modules and some obscure older protocols. Most of that has been fixed in 2.6.
