Although these patches have not been baking in any -mm tree, they have been tested and are generally available as a part of the Cell SDK 2.0 overseen by Arnd Bergmann. (Arnd, if you want to lend a voice of authority here, or to correct me, please do so...) The following sequence of six patches implement a series of changes to the transmit side of the spidernet ethernet device driver, significantly improving performance for large packets. This series of patches is almost identical to those previously mailed on 18-20 August, with one critical change: NAPI polling is used instead of homegrown polling. Although these patches improve things, I am not satisfied with how this driver behaves, and so plan to do additional work next week.
