This is great, not just the parameters themselves but all the steps that a packet follows from the point it enters the NIC until it gets to userspace.

Just one thing to add regarding network performance: if you're working in a system with multiple CPUs (which is usually the case in big servers), check NUMA allocation. Sometimes the network card will be in one CPU while the application is executing on a different one, and that can affect performance too.
