[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.
+
+ See <file:Documentation/networking/NAPI_HOWTO.txt> for more
+ information.
+
+ If in doubt, say N.
