In station mode and AP mode with a single - * BSS every bit matters since we lock to only one BSS.

Some frames that are not for us might get ACKed from us - * by PCU because they just match the mask. - * - * When handling multiple BSSes you can get the BSSID mask by computing the - * set of ~ ( MAC XOR BSSID ) for all bssids we handle. - * - * When you do this you are essentially computing the common bits of all your - * BSSes.

However, if the user *does* manually set the hardware - * source address of a STRIP interface, then the kernel will believe it, - * and use it in certain places. For example, the hardware address listed - * by ifconfig will be the manual address, not the true one. - * (Both addresses are listed in /proc/net/strip.) - * Also, ARP packets will be sent out giving the user-specified address as - * the source address, not the real address. This is dangerous, because - * it means you won't receive any replies -- the ARP replies will go to - * the specified address, which will be some other radio. The case where - * this is useful is when that other radio is also connected to the same - * machine. This allows you to connect a pair of radios to one machine, - * and to use one exclusively for inbound traffic, and the other - * exclusively for outbound traffic. Pretty neat, huh? - * - * Here's the full procedure to set this up: - * - * 1. "slattach" two interfaces, e.g. st0 for outgoing packets, - * and st1 for incoming packets - * - * 2. "ifconfig" st0 (outbound radio) to have the hardware address - * which is the real hardware address of st1 (inbound radio). - * Now when it sends out packets, it will masquerade as st1, and - * replies will be sent to that radio, which is exactly what we want. - * - * 3. Set the route table entry ("route add default ..." or - * "route add -net ...", as appropriate) to send packets via the st0 - * interface (outbound radio). Do not add any route which sends packets - * out via the st1 interface -- that radio is for inbound traffic only. - * - * 4. "ifconfig" st1 (inbound radio) to have hardware address zero. - * This tells the STRIP driver to "shut down" that interface and not - * send any packets through it. In particular, it stops sending the - * periodic gratuitous ARP packets that a STRIP interface normally sends. - * Also, when packets arrive on that interface, it will search the - * interface list to see if there is another interface who's manual - * hardware address matches its own real address (i.e. st0 in this - * example) and if so it will transfer ownership of the skbuff to - * that interface, so that it looks to the kernel as if the packet - * arrived on that interface. This is necessary because when the - * kernel sends an ARP packet on st0, it expects to get a reply on - * st0, and if it sees the reply come from st1 then it will ignore - * it (to be accurate, it puts the entry in the ARP table, but - * labelled in such a way that st0 can't use it). - * - * Thanks to Petros Maniatis for coming up with the idea of splitting - * inbound and outbound traffic between two interfaces, which turned - * out to be really easy to implement, even if it is a bit of a hack. - * - * Having set a manual address on an interface, you can restore it - * to automatic operation (where the address is automatically kept - * consistent with the real address of the radio) by setting a manual - * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF" - * This 'turns off' manual override mode for the device address. - * - * Note: The IEEE 802 headers reported in tcpdump will show the *real* - * radio addresses the packets were sent and received from, so that you - * can see what is really going on with packets, and which interfaces - * they are really going through. - */ - - -/************************************************************************/ -/* Constants */ - -/* - * CommandString1 works on all radios - * Other CommandStrings are only used with firmware that provides structured responses. - * - * ats319=1 Enables Info message for node additions and deletions - * ats319=2 Enables Info message for a new best node - * ats319=4 Enables checksums - * ats319=8 Enables ACK messages - */ - -static const int MaxCommandStringLength = 32; -static const int CompatibilityCommand = 1; - -static const char CommandString0[] = "*&COMMAND*ATS319=7"; /* Turn on checksums & info messages */ -static const char CommandString1[] = "*&COMMAND*ATS305?"; /* Query radio name */ -static const char CommandString2[] = "*&COMMAND*ATS325?"; /* Query battery voltage */ -static const char CommandString3[] = "*&COMMAND*ATS300?"; /* Query version information */ -static const char CommandString4[] = "*&COMMAND*ATS311?"; /* Query poletop list */ -static const char CommandString5[] = "*&COMMAND*AT~LA"; /* Query portables list */ -typedef struct { - const char *string; - long length; -} StringDescriptor; - -static const StringDescriptor CommandString[] = { - {CommandString0, sizeof(CommandString0) - 1}, - {CommandString1, sizeof(CommandString1) - 1}, - {CommandString2, sizeof(CommandString2) - 1}, - {CommandString3, sizeof(CommandString3) - 1}, - {CommandString4, sizeof(CommandString4) - 1}, - {CommandString5, sizeof(CommandString5) - 1} -}; - -#define GOT_ALL_RADIO_INFO(S) \ - ((S)->firmware_version.c[0] && \ - (S)->battery_voltage.c[0] && \ - memcmp(&(S)->true_dev_addr, zero_address.c, sizeof(zero_address))) - -static const char hextable[16] = "0123456789ABCDEF"; - -static const MetricomAddress zero_address; -static const MetricomAddress broadcast_address = - { {0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF} }; - -static const MetricomKey SIP0Key = { "SIP0" }; -static const MetricomKey ARP0Key = { "ARP0" }; -static const MetricomKey ATR_Key = { "ATR " }; -static const MetricomKey ACK_Key = { "ACK_" }; -static const MetricomKey INF_Key = { "INF_" }; -static const MetricomKey ERR_Key = { "ERR_" }; - -static const long MaxARPInterval = 60 * HZ; /* One minute */ - -/* - * Maximum Starmode packet length is 1183 bytes.

As - * the gain would be mostly for SMP systems, it can wait... - * - * Debugging and options - * --------------------- - * You will find below a set of '#define" allowing a very fine control - * on the driver behaviour and the debug messages printed. - * The main options are : - * o SET_PSA_CRC, to have your card correctly recognised by - * an access point and the Point-to-Point diagnostic tool. - * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom) - * (otherwise we always start afresh with some defaults) - * - * wavelan.o is too darned big - * --------------------------- - * That's true! There is a very simple way to reduce the driver - * object by 33%! Comment out the following line: - * #include <linux/wireless.h> - * Other compile options can also reduce the size of it... - * - * MAC address and hardware detection: - * ----------------------------------- - * The detection code for the WaveLAN checks that the first three - * octets of the MAC address fit the company code. This type of - * detection works well for AT&T cards (because the AT&T code is - * hardcoded in wavelan.h), but of course will fail for other - * manufacturers. - * - * If you are sure that your card is derived from the WaveLAN, - * here is the way to configure it: - * 1) Get your MAC address - * a) With your card utilities (wfreqsel, instconf, etc.) - * b) With the driver: - * o compile the kernel with DEBUG_CONFIG_INFO enabled - * o Boot and look the card messages - * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h) - * 3) Compile and verify - * 4) Send me the MAC code.
