Bug description:
[Impact]
* When vlan interfaces are created, their mac address is copied from
the underlying interface, but it is not marked by kernel as stolen.
* When underlying interface MAC address is changed, it does not
propagate to the vlan interfaces.
[Test Case]
* Create vlan interface, check the addr_assign_type sysfs attribute,
it should be 2, not 0.
* Update the base interface mac address, the mac address of the vlan
interface should change too.
[Regression Potential]
* Userspace may rely on non-propagating MAC addresses, and the fact
that vlan mac address type is wrongly stated as non-stolen; however
this behaviour will be consistent with 4.7+ kernels.
[Other Info]
* Please cherrypick 308453aa9156a3b8ee382c0949befb507a32b0c1 into
v4.4 kernels

vlan: Propagate MAC address to VLANs
The MAC address of the physical interface is only copied to the VLAN
when it is first created, resulting in an inconsistency after MAC
address changes of only newly created VLANs having an up-to-date MAC.
The VLANs should continue inheriting the MAC address of the physical
interface until the VLAN MAC address is explicitly set to any value.
This allows IPv6 EUI64 addresses for the VLAN to reflect any changes
to the MAC of the physical interface and thus for DAD to behave as
expected.

* Original bug report
When attempting to verify sru for bug 1669860, I found that vlans
are not properly filtered out by 'get_interfaces_by_mac'. That means
that the bug is still present with vlans.
The reason for this is that /sys/class/net/<vlan_name>/addr_assign_type
shows '0' for a vlan on 4.4, but (correctly) shows '2' on 4.8.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-class-net
for doc on addr_assign_type.
