Merge branch 'net-dev-Make-protocol-ptr-dependent-on-CONFIG'
David Ahern says:
====================
net: dev: Make protocol ptr dependent on CONFIG
Found these in a branch from 3-years ago. Still relevant today.
Make decnet, ax25, and atalk ptrs in net_device based on their
respective CONFIG.
====================
