The KHZ_PER_GHZ might be used by others (with the name aligned
with similar constants). Define it in units.h and convert
wireless to use it.

wireless patches go to wireless-next, not net-next. But no need resend
because of this.

Aha, thanks. Note, I still don't see it in wireless-next tree. Is everything
on track?
