[PATCH] pcnet32: NAPI implementation
Implement NAPI changes to pcnet32 driver. Compile default is off. Listed as experimental. Len and Don both worked on a NAPI implementation and have both tested these changes. An e1000 blasting short packets to the pcnet32 will lockup Don's system until the receive storm stops. Without NAPI Len's system watchdog would expire causing the system to reboot. With NAPI the system will stay operational. Tested ia32 and ppc64. Tested '970A, '971, '972, '973, '975, '976, and '978. The Kconfig changes came from Len. Don is to blame for all the others.

+ 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.
