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!

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.
