- * @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.
