-+ * ieee80211_radiotap_iterator_init - radiotap parser iterator initialization
-+ * @iterator: radiotap_iterator to initialize
-+ * @radiotap_header: radiotap header to parse
-+ * @max_length: total length we can parse into (eg, whole packet length)
-+ *
-+ * Returns: 0 or a negative error code if there is a problem.
-+ *
-+ * This function initializes an opaque iterator struct which can then
-+ * be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
-+ * argument which is present in the header. It knows about extended
-+ * present headers and handles them.
-+ *
-+ * How to use:
-+ * call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
-+ * struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
-+ * checking for a good 0 return code. Then loop calling
-+ * __ieee80211_radiotap_iterator_next()... it returns either 0,
-+ * -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
-+ * The iterator's @this_arg member points to the start of the argument
-+ * associated with the current argument index that is present, which can be
-+ * found in the iterator's @this_arg_index member. This arg index corresponds
-+ * to the IEEE80211_RADIOTAP_... defines.
-+ *
-+ * Radiotap header length:
-+ * You can find the CPU-endian total radiotap header length in
-+ * iterator->max_length after executing ieee80211_radiotap_iterator_init()
-+ * successfully.
-+ *
-+ * Alignment Gotcha:
-+ * You must take care when dereferencing iterator.this_arg
-+ * for multibyte types... the pointer is not aligned. Use
-+ * get_unaligned((type *)iterator.this_arg) to dereference
-+ * iterator.this_arg for type "type" safely on all arches.
