- * 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.
- *
- * Example code:
- * See Documentation/networking/radiotap-headers.txt

++ * 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.
