If you have one of those product, you will need to ! 23: * make some changes below... ! 24: * ! 25: * This driver is still a beta software. A lot of bugs have been corrected, ! 26: * a lot of functionalities are implemented, the whole appear pretty stable, ! 27: * but there is still some area of improvement (encryption, performance...). ! 28: * ! 29: * To know how to use this driver, read the NET3 HOWTO. ! 30: * If you want to exploit the many other fonctionalities, look comments ! 31: * in the code... ! 32: * ! 33: * This driver is the result of the effort of many peoples (see below). ! 34: */ ! 35: ! 36: /* ------------------------ SPECIFIC NOTES ------------------------ */ ! 37: /* ! 38: * wavelan.o is darn too big ! 39: * ------------------------- ! 40: * That's true ! There is a very simple way to reduce the driver ! 41: * object by 33% (yes !). Comment out the following line : ! 42: * #include <linux/wireless.h> ! 43: * ! 44: * MAC address and hardware detection : ! 45: * ---------------------------------- ! 46: * The detection code of the wavelan chech that the first 3 ! 47: * octets of the MAC address fit the company code. This type of ! 48: * detection work well for AT&T cards (because the AT&T code is ! 49: * hardcoded in wavelan.h), but of course will fail for other ! 50: * manufacturer. ! 51: * ! 52: * If you are sure that your card is derived from the wavelan, ! 53: * here is the way to configure it : ! 54: * 1) Get your MAC address ! 55: * a) With your card utilities (wfreqsel, instconf, ...) ! 56: * b) With the driver : ! 57: * o compile the kernel with DEBUG_CONFIG_INFO enabled ! 58: * o Boot and look the card messages ! 59: * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h) ! 60: * 3) Compile & verify ! 61: * 4) Send me the MAC code - I will include it in the next version... ! 62: * ! 63: * "CU Inactive" message at boot up : ! 64: * ----------------------------------- ! 65: * It seem that there is some weird timings problems with the ! 66: * Intel microcontroler. In fact, this message is triggered by a ! 67: * bad reading of the on board ram the first time we read the ! 68: * control block. If you ignore this message, all is ok (but in ! 69: * fact, currently, it reset the wavelan hardware). ! 70: * ! 71: * To get rid of that problem, there is two solution. The first ! 72: * is to add a dummy read of the scb at the end of ! 73: * wv_82586_config. The second is to add the timers ! 74: * wv_synchronous_cmd and wv_ack (the udelay just after the ! 75: * waiting loops - seem that the controler is not totally ready ! 76: * when it say it is !). ! 77: * ! 78: * In the current code, I use the second solution (to be ! 79: * consistent with the original solution of Bruce Janson). ! 80: */ ! 81: ! 82: /* --------------------- WIRELESS EXTENSIONS --------------------- */ ! 83: /* ! 84: * This driver is the first one to support "wireless extensions". ! 85: * This set of extensions provide you some way to control the wireless ! 86: * caracteristics of the hardware in a standard way and support for ! 87: * applications for taking advantage of it (like Mobile IP). ! 88: * ! 89: * You will need to enable the CONFIG_NET_RADIO define in the kernel ! 90: * configuration to enable the wireless extensions (this is the one ! 91: * giving access to the radio network device choice). ! 92: * ! 93: * It might also be a good idea as well to fetch the wireless tools to ! 94: * configure the device and play a bit. ! 95: */ ! 96: ! 97: /* ---------------------------- FILES ---------------------------- */ ! 98: /* ! 99: * wavelan.c : The actual code for the driver - C functions ! 100: * ! 101: * wavelan.p.h : Private header : local types / vars for the driver ! 102: * ! 103: * wavelan.h : Description of the hardware interface & structs ! 104: * ! 105: * i82586.h : Description if the Ethernet controler ! 106: */ ! 107: ! 108: /* --------------------------- HISTORY --------------------------- */ ! 109: /* ! 110: * (Made with information in drivers headers.
