Testers needed for ham radio patches

I've cooked a series of patches that convert most of the ham radio drivers and core code to convert them to use the netdev_priv() macro which was introduced a while ago. Lacking all the hardware for testing in the hope for testers. I left out the SCC and DMASCC drivers; they're looking too scarry to touch without having hardware.

The patches are compile tested and I consider them low risk, so probably safe to merged right away if you'd like.
