The following series of patches implement some fixes and 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
These have been well-tested over the last few weeks. Please apply.
With these patches the spidernet driver performance goes from bad to usable. They are all
good changes. I'd expect some more bottlnecks to be identified now that these are
cleared. Maybe Jim and Linas can get the driver performance up from usable to good next.
