MIPS: PowerTV: Base files for Cisco PowerTV platform
Add the Cisco Powertv cable settop box to the MIPS tree. This platform is based on a MIPS 24Kc processor with various devices integrated on the same ASIC. There are multiple models of this box, with differing configuration but the same kernel runs across the product line.

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.
