+/*
+ * RF Buffer register
+ *
+ * There are some special control registers on the RF chip
+ * that hold various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the buffer register and
+ * then write on another special register to notify hw
+ * to apply the settings. 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. So i'll name them BUFFER_CONTROL_X registers
+ * for now. It's interesting that they are also used for some other operations.
+ *
+ * Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
+ * registers and control registers):
+ *
+ * http://www.google.com/patents?id=qNURAAAAEBAJ
