285 * Generates an Ethernet MAC address that is highly likely to be unique for
286 * this particular system on a network with other systems of the same type.
287 *
288 * The problem we are solving is that, when random_ether_addr() is used to
289 * generate MAC addresses at startup, there isn't much entropy for the random
290 * number generator to use and the addresses it produces are fairly likely to
291 * be the same as those of other identical systems on the same local network.
292 * This is true even for relatively small numbers of systems (for the reason
293 * why, see the Wikipedia entry for "Birthday problem" at:
294 * http://en.wikipedia.org/wiki/Birthday_problem
295 *
296 * The good news is that we already have a MAC address known to be unique, the
297 * RF MAC address. The bad news is that this address is already in use on the
298 * RF interface. Worse, the obvious trick, taking the RF MAC address and
299 * turning on the locally managed bit, has already been used for other devices.
300 * Still, this does give us something to work with.
301 *
302 * The approach we take is:
303 * 1. If we can't get the RF MAC Address, just call random_ether_addr.
304 * 2. Use the 24-bit NIC-specific bits of the RF MAC address as the last 24
305 * bits of the new address. This is very likely to be unique, except for
306 * the current box.
307 * 3. To avoid using addresses already on the current box, we set the top
308 * six bits of the address with a value different from any currently
309 * registered Scientific Atlanta organizationally unique identifyer
310 * (OUI). This avoids duplication with any addresses on the system that
311 * were generated from valid Scientific Atlanta-registered address by
312 * simply flipping the locally managed bit.
313 * 4. We aren't generating a multicast address, so we leave the multicast
314 * bit off. Since we aren't using a registered address, we have to set
315 * the locally managed bit.
316 * 5. We then randomly generate the remaining 16-bits. This does two
317 * things:
318 * a. It allows us to call this function for more than one device
319 * in this system
320 * b. It ensures that things will probably still work even if
321 * some device on the device network has a locally managed
322 * address that matches the top six bits from step 2.
