any layer can use the cb structure whichever way they wish. There are violations, e.g: the vlan code also uses the cb field to pass vlan details for hardware acceleration. How does pktgen affect it though, clone() will just copy the cb field and pktgen doesnt touch it. In retrospect, pktgen may have to use clone - ccing Robert Olsson. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
