Jeff, the following patches replace current PowerPC 4xx EMAC driver with new, re-written version.
New driver uses NAPI, it solves problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now :). This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts were just posted to linuxppc-dev and linuxppc-embedded mail lists. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.
