* 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
