Going the multipacket approach seems a bit more tricky, hence it involves changing the TCP and posibly also if_output() calls needs to handle this aswell, though not impossible. lstewart: What should an mbuf accessor that computes the total pktheader payload for multiple mbufs be called? m_pkthdr_chain_length(m) ??
