Most, if not all, changes in wireless extensions were backwards
compatible at least in the source level. From my viewpoint, it's quite
a bit different to start removing function arguments..

Well.. I can understand the goal of having a clean interface to internal
kernel functionality. Yes, it will mean things get broken every now and
then, but then again, one can go the route of taking a distro kernel and

I didn't get much (well, none) comments on this when I submitted the
driver for wireless-2.6 tree. I could try to update wireless-2.6 version
to match with my current work version and then ask whether it could be
