The set_multicast_list function may be called without holding the rtnl mutex, resulting in races when changing the underlying device's promiscous and allmulti state. Use the change_rx_mode hook, which is always invoked under the rtnl. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
