Basically, add a new dev_add_addr hook to netdevice.
Drivers that can do it, would add the hook. If driver didn't have hook,
then core would put device into promiscuous.  Most devices with multicast
allow non-multicast addresses, so it could be a simple extension.
Rather than doing it for all devices, wanted to go in one by one and test.
