- * ieee80211_radiotap_iterator_init - radiotap parser iterator initialization
- * @param iterator: radiotap_iterator to initialize
- * @param radiotap_header: radiotap header to parse
- * @param max_length: total length we can parse into (eg, whole packet length)
- *
- * @return 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.
- *
- * Example code:
- * See Documentation/networking/radiotap-headers.txt
