This has nothing to do with Kconfig files, I assume you meant Makefiles.

There is no duplication needed, drivers/net/Makefile needs to contain
obj-y += intel_wired_lan/ and drivers/net/intel_wired_lan/Makefile
similar lines for its subdirs. I see your original patch was lacking an
entry in drivers/net/Makefile, so perhaps that was the problem Jeff was
seeing?
