Add NAPI support to the via-rhine driver so that it can handle higher
speeds and doesn't get overloaded by interrupts as easily.

+          NAPI is a new driver API designed to reduce CPU and interrupt load
+          when the driver is receiving lots of packets from the card.
+
+          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.
