Aragh of course the linux headers are doing the work not NetworkManagment.

Sorry about that Thomas and thanks for getting back to me. I have to find out
a bit of info. I've cross compiled my own kernel 3.18.13 on my laptop but I've
not copied across the kernel source RPi as I'm not sure where to put it so
that it's picked up by the build process. I suppose /usr/src/linux?
