-	  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.
