No, only dev->mc is looked at. It was set for all the lists of a device
after Nicolas's comment on v7:

```
  There are several lists owned by a device (dev->dev_addrs, dev->uc,
  dev->mc, dev->rx_mode_addr_cache), the name 'owner' does not reflect
  that it is set only when the list is dev->mc.
  I wonder if the name should be changed or if __hw_addr_init() should
  be updated to always set owner when the list is owned by a device.
```

v10 takes the other option: the field becomes mc_dev, set for dev->mc
only.
