Hmmm, doesn't this change behavior?
For the handling of the NETDEV_CHANGEADDR event in macvlan_device_event()
we would make it to macvlan_sync_address(), and if IFF_UP is false,
we would elide the macvlan_addr_busy() check and just copy the MAC addres
over and return.
Now, we would always perform the macvlan_addr_busy() check.
Please, if this is OK, explain and document this behavioral chance in
the commit message.
Thank you.
