The now deFacto pre-Linux kernel, the -mm tree now has a completely re-done and sane WiFi core.
It should make many thing that are currently difficult at best, impossible at worst for most any Wireless card (including one that use ndiswrapper), transforming that problem into a non-issue period.
Now, for those of use using ndiswrapper and other "on-crack" drivers for the wireless cards they have... this event is the most important one I have seen for a while in the linux kernel.
If it really does well, by ways of the API/ABI, types of interfaces to be changed and easily backward compatible, I'd expect to see a complete re-working of the entire "device subsystems" structure in Linux. Of course, I am hope, but if my tidbits from Greg Kroah-Hartman is any indication of just how good the upcoming chnages are, we should see linux become ubiquitous for any hardware, literally any hardware.
