Just for your information, it's actually trivial to cache
parameters in the driver and to apply them in one go using the WE
commit mechanism. It's actually even strongly advised, as it make the
startup performance much better (fewer reset of the hardware).
Many drivers do implement this, such as orinoco.c, atmel.c,
airo.c (partial) and ray_cs.c. The performance benefit of implementing
it in orinoco.c was actually noticeable.
The current API is flexible and allow you to have it both
way. When I designed it, I actually thought about passing a big struct
with all the parameters to the driver and rejected it because too
inflexible. It's even documented in iw_handler.h, and I list other
drawbacks of the approach.
Pedro, if you want more detail of the commit stuff, please
yell...
Have fun...
