[PATCH] uml: use get_random_bytes() after random pool is seeded
When the UML network driver generates random MACs for its devices, it was possible for a number of UMLs to get the same MACs because the ethernet initialization was done before the random pool was properly seeded. This patch moves the initialization later so that it gets better randomness.
