[PATCH] forcdeth: revised NAPI support

Revised version of the forcedeth NAPI support.
This version is based against netdev-2.6#upstream
(after the MAC patches from Ayaz today).

Can't use nv_disable_hw_interrupts because NAPI only wants to
mask off receive irq's and leave the others alone.

+          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.
