+ * The "old" table matches devices based on PCI vendor/product IDs only.
+ * The "new" table extends this with various device parameters derived
+ * from MAC type, and RF type.
+ *
+ * In iwlwifi "old" and "new" tables share the same array, where "old"
+ * entries contain dummy values for data defined only for "new" entries.
+ * As of 2022, Linux developers are still in the process of moving entries
+ * from "old" to "new" style and it looks like this effort has stalled in
+ * in some work-in-progress state for quite a while. Linux commits moving
+ * entries from "old" to "new" have at times been reverted due to regressions.
+ * Part of this complexity comes from iwlwifi supporting both iwm(4) and iwx(4)
+ * devices in the same driver.
+ *
+ * Our table below contains mostly "new" entries declared in iwlwifi
+ * with the _IWL_DEV_INFO() macro (with a leading underscore).
+ * Other devices are matched based on PCI vendor/product ID as usual,
+ * unless matching specific PCI subsystem vendor/product IDs is required.
+ *
+ * Some "old"-style entries are required to identify the firmware image to use.
+ * Others might be used to print a specific marketing name into Linux dmesg,
+ * but we can't be sure whether the corresponding devices would be matched
+ * correctly in the absence of their entries. So we include them just in case.

+/**
+ * DOC: Time Events - what is it?
+ *
+ * Time Events are a fw feature that allows the driver to control the presence
+ * of the device on the channel. Since the fw supports multiple channels
+ * concurrently, the fw may choose to jump to another channel at any time.
+ * In order to make sure that the fw is on a specific channel at a certain time
+ * and for a certain duration, the driver needs to issue a time event.
+ *
+ * The simplest example is for BSS association. The driver issues a time event,
+ * waits for it to start, and only then tells mac80211 that we can start the
+ * association. This way, we make sure that the association will be done
+ * smoothly and won't be interrupted by channel switch decided within the fw.
+ */
+
+ /**
+ * DOC: The flow against the fw
+ *
+ * When the driver needs to make sure we are in a certain channel, at a certain
+ * time and for a certain duration, it sends a Time Event. The flow against the
+ * fw goes like this:
+ * 1) Driver sends a TIME_EVENT_CMD to the fw
+ * 2) Driver gets the response for that command. This response contains the
+ * Unique ID (UID) of the event.
+ * 3) The fw sends notification when the event starts.
+ *
+ * Of course the API provides various options that allow to cover parameters
+ * of the flow.
+ * What is the duration of the event?
+ * What is the start time of the event?
+ * Is there an end-time for the event?
+ * How much can the event be delayed?
+ * Can the event be split?
+ * If yes what is the maximal number of chunks?
+ * etc...
