'function' should replace this. Don't encourage more users. 

Also, 'netdev' is not documented which leaves me wondering why there's 
no warning? Either this patch didn't apply or there's a problem in the 
schema that's not checking this node.

Typo? These are supposed to be unique. Can't you use 'reg' in your case?
