NAPI
----
NAPI (Rx polling mode) is supported in the e1000 driver. NAPI is enabled
or disabled based on the configuration of the kernel. To override
the default, use the following compile-time flags.

To enable NAPI, compile the driver module, passing in a configuration option:

make CFLAGS_EXTRA=-DE1000_NAPI install

To disable NAPI, compile the driver module, passing in a configuration option:

make CFLAGS_EXTRA=-DE1000_NO_NAPI install
NAPI (Rx polling mode) is enabled in the e1000 driver.

See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.

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.
