dev: introduce dev_get_iflink()
The goal of this patch is to prepare the removal of the iflink field. It introduces a new ndo function, which will be implemented by virtual interfaces. There is no functional change into this patch. All readers of iflink field now call dev_get_iflink(). Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>
