I suspect that for many targets and configurations, the local arrays might actually be smaller than exporting a global. You have to factor in not just the .text size, but the fact that referencing an exported symbol needs a .reloc entry as well, which also eats up some space (at least when the code is being built as module).
In my opinion, your series probably causes more bloat in common configurations instead of reducing it. You're also touching several places that could easily use eth_broadcast_addr and eth_zero_addr. I think making those changes would be more productive than what you did in this series. - Felix
