Right now the various input routines do not expect a chain of packets and probably assume that the chain is a single packet. I assume you mean that the chain here represents a single mbuf still and they are chained via m_next and not m_nextpkt? I suspect that this is probably fine and that most things will only check for M_PKTHDR and look for the fields in the first mbuf in the chain. -- John Baldwin _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
