Sure, will do, I actually think there's an endian bug or two in this
driver that sparse catches
once you suppress the spew coming out of the
VMXNET_{READ,WRITE}_BAR{0,1} macros.

Why is this driver byteswapping everything to little-endian before
sticking it into writel()?  Isn't
writel() defined to write out in little-endian as per PCI?  Similarly
for swapping whatever it reads
in from readl()?

What am I missing?
