-        help
-          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.
-
-          If in doubt, say N.
