Excellent -- netstat support for monitoring queue and RSS behaviour is definitely the next step to run in, here. I'd like to see us extend the kernel's device-driver independent data structures and statistics to allow interfaces to expose additional hardware queue information/statistics as well as higher-level netisr, pcbgroup, and RSS information.
