net: dev: Issue NETDEV_PRE_CHANGEADDR
When a device address is about to be changed, or an address added to the list of device HW addresses, it is necessary to ensure that all interested parties can support the address. Therefore, send the NETDEV_PRE_CHANGEADDR notification, and if anyone bails on it, do not change the address. Signed-off-by:Petr Machata <petrm@mellanox.com> Acked-by:
