This is precisely something I need to do. We need to estimate the
amount of time a packet spends in the kernel until it's considered
'sent' out the wire. While I ramp up on SystemTap if anyone has an
answer to this, an example script, or anything that can assist in this I
would also love to see it and/or hear discussion about it.

Lukas Hejtmanek is looking at profiling the network stack and routing
in the linux kernel. This looks like a very typical application of
SystemTap.
