The high point of the patch series is some code to implement a low-watermark interrupt on the transmit queue. The bundle of patches raises transmit performance from some embarassingly low value to a reasonable 730 Megabits per second for 1500 byte packets. Please note that the spider is an ethernet controller that is integrated into the south bridge, and is thus available only on Cell-based platforms. These have been well-tested over the last few weeks. Please apply. --linas
