pointer to the radiotap header we are walking through


vendor namespace definitions


pointer to the current namespace definition (or internally NULL if the current namespace is unknown)


next argument pointer


beginning of the next namespace's data


internal pointer to next present u32


pointer to current radiotap arg; it is valid after each call to ieee80211_radiotap_iterator_next but also after ieee80211_radiotap_iterator_init where it will point to the beginning of the actual data portion


index of current arg, valid after each successful call to ieee80211_radiotap_iterator_next


length of the current arg, for convenience


indicates whether the current namespace is the default radiotap namespace or not


length of radiotap header in cpu byte ordering


next argument index


internal shifter for curr u32 bitmap, b0 set == arg present


internal; reset the arg index to 0 when going to the next bitmap word
