It is used in a few places:

net/ethernet/litex/Kconfig:	depends on OF_NET
net/ethernet/amd/Kconfig:	depends on ((OF_NET && OF_ADDRESS) || ACPI || PCI) && HAS_IOMEM
net/ethernet/mscc/Kconfig:	depends on OF_NET
net/ethernet/ezchip/Kconfig:	depends on OF_IRQ && OF_NET
net/ethernet/arc/Kconfig:	depends on OF_IRQ && OF_NET
net/ethernet/arc/Kconfig:	depends on OF_IRQ && OF_NET && REGULATOR

so it cannot just disappear. These will need reviewing and changing as
well.
