251 * Generate an Ethernet MAC address that has a good chance of being unique.
252 * @addr: Pointer to six-byte array containing the Ethernet address
253 * Generates an Ethernet MAC address that is highly likely to be unique for
254 * this particular system on a network with other systems of the same type.
255 *
256 * The problem we are solving is that, when eth_random_addr() is used to
257 * generate MAC addresses at startup, there isn't much entropy for the random
258 * number generator to use and the addresses it produces are fairly likely to
259 * be the same as those of other identical systems on the same local network.
260 * This is true even for relatively small numbers of systems (for the reason
261 * why, see the Wikipedia entry for "Birthday problem" at:
262 * http://en.wikipedia.org/wiki/Birthday_problem
263 *
264 * The good news is that we already have a MAC address known to be unique, the
265 * RF MAC address. The bad news is that this address is already in use on the
266 * RF interface. Worse, the obvious trick, taking the RF MAC address and
267 * turning on the locally managed bit, has already been used for other devices.
268 * Still, this does give us something to work with.
269 *
270 * The approach we take is:
271 * 1. If we can't get the RF MAC Address, just call eth_random_addr.
272 * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
273 * bits of the new address. This is very likely to be unique, except for
274 * the current box.
275 * 3. To avoid using addresses already on the current box, we set the top
276 * six bits of the address with a value different from any currently
277 * registered Scientific Atlanta organizationally unique identifyer
278 * (OUI). This avoids duplication with any addresses on the system that
279 * were generated from valid Scientific Atlanta-registered address by
280 * simply flipping the locally managed bit.
281 * 4. We aren't generating a multicast address, so we leave the multicast
282 * bit off. Since we aren't using a registered address, we have to set
283 * the locally managed bit.
284 * 5. We then randomly generate the remaining 16-bits. This does two
285 * things:
286 * a. It allows us to call this function for more than one device
287 * in this system
288 * b. It ensures that things will probably still work even if
289 * some device on the device network has a locally managed
290 * address that matches the top six bits from step 2.
