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.
