22 Say Y if you have a Metricom radio and intend to use Starmode Radio
23 IP. STRIP is a radio protocol developed for the MosquitoNet project
24 (on the WWW at <http://mosquitonet.stanford.edu/>) to send Internet
25 traffic using Metricom radios. Metricom radios are small, battery
26 powered, 100kbit/sec packet radio transceivers, about the size and
27 weight of a cellular telephone. (You may also have heard them called
28 "Metricom modems" but we avoid the term "modem" because it misleads
29 many people into thinking that you can plug a Metricom modem into a
30 phone line and use it as a modem.)
31
32 You can use STRIP on any Linux machine with a serial port, although
33 it is obviously most useful for people with laptop computers. If you
34 think you might get a Metricom radio in the future, there is no harm
35 in saying Y to STRIP now, except that it makes the kernel a bit
36 bigger.
37
38 To compile this as a module, choose M here: the module will be
39 called strip.

300 * Note: manual_dev_addr hack
301 *
302 * It is not possible to change the hardware address of a Metricom radio,
303 * or to send packets with a user-specified hardware source address, thus
304 * trying to manually set a hardware source address is a questionable
305 * thing to do. However, if the user *does* manually set the hardware
306 * source address of a STRIP interface, then the kernel will believe it,
307 * and use it in certain places. For example, the hardware address listed
308 * by ifconfig will be the manual address, not the true one.
309 * (Both addresses are listed in /proc/net/strip.)
310 * Also, ARP packets will be sent out giving the user-specified address as
311 * the source address, not the real address. This is dangerous, because
312 * it means you won't receive any replies -- the ARP replies will go to
313 * the specified address, which will be some other radio. The case where
314 * this is useful is when that other radio is also connected to the same
315 * machine. This allows you to connect a pair of radios to one machine,
316 * and to use one exclusively for inbound traffic, and the other
317 * exclusively for outbound traffic. Pretty neat, huh?
318 *
319 * Here's the full procedure to set this up:
320 *
321 * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
322 * and st1 for incoming packets
323 *
324 * 2. "ifconfig" st0 (outbound radio) to have the hardware address
325 * which is the real hardware address of st1 (inbound radio).
326 * Now when it sends out packets, it will masquerade as st1, and
327 * replies will be sent to that radio, which is exactly what we want.
328 *
329 * 3. Set the route table entry ("route add default ..." or
330 * "route add -net ...", as appropriate) to send packets via the st0
331 * interface (outbound radio). Do not add any route which sends packets
332 * out via the st1 interface -- that radio is for inbound traffic only.
333 *
334 * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
335 * This tells the STRIP driver to "shut down" that interface and not
336 * send any packets through it. In particular, it stops sending the
337 * periodic gratuitous ARP packets that a STRIP interface normally sends.
338 * Also, when packets arrive on that interface, it will search the
339 * interface list to see if there is another interface who's manual
340 * hardware address matches its own real address (i.e. st0 in this
341 * example) and if so it will transfer ownership of the skbuff to
342 * that interface, so that it looks to the kernel as if the packet
343 * arrived on that interface. This is necessary because when the
344 * kernel sends an ARP packet on st0, it expects to get a reply on
345 * st0, and if it sees the reply come from st1 then it will ignore
346 * it (to be accurate, it puts the entry in the ARP table, but
347 * labelled in such a way that st0 can't use it).
348 *
349 * Thanks to Petros Maniatis for coming up with the idea of splitting
350 * inbound and outbound traffic between two interfaces, which turned
351 * out to be really easy to implement, even if it is a bit of a hack.
352 *
353 * Having set a manual address on an interface, you can restore it
354 * to automatic operation (where the address is automatically kept
355 * consistent with the real address of the radio) by setting a manual
356 * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
357 * This 'turns off' manual override mode for the device address.
358 *
359 * Note: The IEEE 802 headers reported in tcpdump will show the *real*
360 * radio addresses the packets were sent and received from, so that you
361 * can see what is really going on with packets, and which interfaces
362 * they are really going through.
