So perhaps I should provide some more context into why I'm sending these
patches. The following hardware is currently available and the existing
Linux support is confined to a Timesys Fedora-Based pre-installed image
which requires user intervention to write a MAC using an old, not
upstreamed, modified ioh_gbe_mac driver.

The board documentation is available here:
http://www.inforcecomputing.com/SYS940X_ECX.html

In particular, see:
http://www.inforcecomputing.com/proddls/SYS940X-01_UserGuide_001329.pdf
and:
http://www.inforcecomputing.com/proddls/BLDK2_Kern_2.6.29-10_and_2.6.29-12_for_SYS940X-1_1304.pdf

I felt this patch made this hardware more accessible by allowing it to
work with current kernels without ugly userspace hacks. It is also
following precedent set by existing drivers.

So while I completely agree with the sentiment "Ship functional
hardware", this wasn't a product I was involved with, I'm just trying to
make a bad situation better. As Alan alludes to above, I do actually
spend a good deal of time trying to improve hardware to avoid this kind
of thing (it's an amazingly difficult task).
