I plan to create (and recreate) thousands of these, and it will be less efficient to
have to rename each of them, as well as making user-space code more complex.

I too was looking at the hostap testing code, and the ability to specify names
of wiphy and the stations on creation time (as some of my other patches allow)
should simplify such testing, as well as my own testing needs.

I have patches to enable hostap to use the kernel features, but have not posted
them since kernel patches are still in flux.

Thanks,
Ben
