I don't know what you are refering to with "new version", but the latest
release, i.e., WE-19, does include linux/types.h, linux/socket.h, and
linux/if.h.

Changes of the drivers should not affect (well, assuming they would use
just Linux Wireless Extensions), but changes of WE do indeed affect user
space programs.

Because linux/wireless.h cannot be included in user space programs
without major compatibility problems with libc header files. Another
reason is in being able to build one binary that supports multiple WE
versions.

No, the license of iwlib is not compatible with hostapd/wpa_supplicant.

I cannot accept changes to hostapd/wpa_supplicant that would make them
GPL only. I'm fine with the change that went already in into subversion,
i.e., just #ifdef __KERNEL__ around all include statements in header
files that are also linked into user space programs. I can include
whatever libc headers I want to make this work for
hostapd/wpa_supplicant and the header files are still functional for the
kernel code without any other changes.

Thanks. I'll take a closer look at this, but that may have to wait till
Saturday.

What changes are needed on the driver side?
