Hi, i have a problem. I need to identify packets (IPv6) across the linux networking code. But there is no ID field as it used to be in ipv4.. what would you advice to distinguish packets on its way through linux router? One restriction is not to change the payload of the packet bcause it requires full memory read to get pkt. id from payload data.. what is your point of view..? regards adam - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
