+ * 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 random_ether_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 random_ether_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.
