Thank you very much, it's much clear now. I have one more question about the other hardware relevant fields in 'struct net_device': 'base_addr' and '[r]mem_start/end'. Why is 'base_addr' recommended to be assigned during device probe, and not later when we can be sure we do need this resource? And I didn't notice '8139too' driver uses '[r]mem_start', '[r]mem_end', isn't it mandatory?
I don't have much idea about net_device, but the fields that you are referring to are quite obsolete, I think. And hence not much drivers use them today.
