│ CONFIG_E1000_NAPI: │ │ │ │ NAPI is a new driver API designed to reduce CPU and interrupt load │ │ when the driver is receiving lots of packets from the card. It is │ │ still somewhat experimental and thus not yet enabled by default. │ │ │ │ If your estimated Rx load is 10kpps or more, or if the card will be │ │ deployed on potentially unfriendly networks (e.g. in a firewall), │ │ then say Y here.
