This is done so that control registers - * can be dynamicaly programmed during operation and the settings - * are applied faster on the hw. - * - * We sent such data packets during rf initialization and channel change - * through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions. - * - * The data packets we send during initializadion are inside ath5k_ini_rf - * struct (see ath5k_hw.h) and each one is related to an "rf register bank". - * We use *rfregs functions to modify them acording to current operation - * mode and eeprom values and pass them all together to the chip. - * * It's obvious from the code that 0x989c is the buffer register but * for the other special registers that we write to after sending each * packet, i have no idea.
