If the device is down, then we simply copy the new address to dev->dev_addr. If the device is up, then we add another loopback device with the new address, and if that does not fail, we remove the loopback device with the old address. And only then, we update the dev->dev_addr. Signed-off-by: Daniel Borkmann <daniel.borkm...@tik.ee.ethz.ch> Signed-off-by: David S.
