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.
