net: Allow for more then a single subclass for netif_addr_lock
Currently netif_addr_lock_nested assumes that there can be only a single nesting level between 2 devices. However, if we have multiple devices of the same type stacked, this fails. For example: eth0 <-- vlan0.10 <-- vlan0.10.20 A more complicated configuration may stack more then one type of device in different order. Ex: eth0 <-- vlan0.10 <-- macvlan0 <-- vlan1.10.20 <-- macvlan1 This patch adds an ndo_* function that allows each stackable device to report its nesting level. If the device doesn't provide this function default subclass of 1 is used. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
