I guess you're right, sorry.

Currently I massively use kernel's MMIO tracing to compare wl hybrid
with b43. After comparing dumps from wl and b43 I noticed tables we
wrote from spect fot bytes swapped for PHY registers values. It also
makes more sense to swap bytes if you simply compare values. Now
values are slightly nicely increasing/decreasing in tables.

If someone is interested in the way I dump operations, please just
ask, I'll provide my /toolchain/.
