* Generate an Ethernet MAC address that has a good chance of being unique.
* @addr: Pointer to six-byte array containing the Ethernet address
* Generates an Ethernet MAC address that is highly likely to be unique for
* this particular system on a network with other systems of the same type.
*
* The problem we are solving is that, when eth_random_addr() is used to
* generate MAC addresses at startup, there isn't much entropy for the random
* number generator to use and the addresses it produces are fairly likely to
* be the same as those of other identical systems on the same local network.
* This is true even for relatively small numbers of systems (for the reason
* why, see the Wikipedia entry for "Birthday problem" at:
* http://en.wikipedia.org/wiki/Birthday_problem
*
* The good news is that we already have a MAC address known to be unique, the
* RF MAC address. The bad news is that this address is already in use on the
* RF interface. Worse, the obvious trick, taking the RF MAC address and
* turning on the locally managed bit, has already been used for other devices.
* Still, this does give us something to work with.
*
* The approach we take is:
* 1. If we can't get the RF MAC Address, just call eth_random_addr.
* 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
* bits of the new address. This is very likely to be unique, except for
* the current box.
* 3. To avoid using addresses already on the current box, we set the top
* six bits of the address with a value different from any currently
* registered Scientific Atlanta organizationally unique identifyer
* (OUI). This avoids duplication with any addresses on the system that
* were generated from valid Scientific Atlanta-registered address by
* simply flipping the locally managed bit.
* 4. We aren't generating a multicast address, so we leave the multicast
* bit off. Since we aren't using a registered address, we have to set
* the locally managed bit.
* 5. We then randomly generate the remaining 16-bits. This does two
* things:
* a. It allows us to call this function for more than one device
* in this system
* b. It ensures that things will probably still work even if
* some device on the device network has a locally managed
* address that matches the top six bits from step 2.
