Merge branch 'r8152-next'

Hayes Wang says:

====================
r8152: random MAC address

If the interface has invalid MAC address, it couldn't
be used. In order to let it work normally, give a
random one.

v3:
  Remove
	ether_addr_copy(dev->perm_addr, dev->dev_addr);

v2:
  Use "%pM" format specifier for printing a MAC address.
