I need the NetFlow data format, not something else.

NetFlow is not based on ASN.1. It's a completely different format (an industry standard which is implemented by quite a few vendors).

I fear the performance impact of copying all packet headers to user space.

I'd like to see something which has virtually no impact on forwarding, so that it's a no-brainer to enable it. I doubt copying all the packet headers to user space falls into this category. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
