+ * The need for this function arises from the fact that we have 4 separate
+ * HW timer registers (TIMER0 - TIMER3), which are closely related to the
+ * next beacon target time (NBTT), and that the HW updates these timers
+ * seperately based on the current TSF value. The hardware increments each
+ * timer by the beacon interval, when the local TSF coverted to TU is equal
+ * to the value stored in the timer.
+ *
+ * The reception of a beacon with the same BSSID can update the local HW TSF
+ * at any time - this is something we can't avoid. If the TSF jumps to a
+ * time which is later than the time stored in a timer, this timer will not
+ * be updated until the TSF in TU wraps around at 16 bit (the size of the
+ * timers) and reaches the time which is stored in the timer.
+ *
+ * The problem is that these timers are closely related to TIMER0 (NBTT) and
+ * that they define a time "window". When the TSF jumps between two timers
+ * (e.g. ATIM and NBTT), the one in the past will be left behind (not
+ * updated), while the one in the future will be updated every beacon
+ * interval. This causes the window to get larger, until the TSF wraps
+ * around as described above and the timer which was left behind gets
+ * updated again. But - because the beacon interval is usually not an exact
+ * divisor of the size of the timers (16 bit), an unwanted "window" between
+ * these timers has developed!
+ *
+ * This is especially important with the ATIM window, because during
+ * the ATIM window only ATIM frames and no data frames are allowed to be
+ * sent, which creates transmission pauses after each beacon. This symptom
+ * has been described as "ramping ping" because ping times increase linearly
+ * for some time and then drop down again. A wrong window on the DMA beacon
+ * timer has the same effect, so we check for these two conditions.
+ *
+ * Returns true if O.K.

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel. We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware. This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel. There is no corresponding channel information for that
+ * entry.
