Detailed Description

struct ieee80211_radiotap_iterator - tracks walk thru present radiotap args : index of current arg, valid after each successful call to ieee80211_radiotap_iterator_next() : 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 : length of the current arg, for convenience : pointer to the current namespace definition (or internally NULL if the current namespace is unknown) : indicates whether the current namespace is the default radiotap namespace or not

: pointer to the radiotap header we are walking through : length of radiotap header in cpu byte ordering : next argument index : next argument pointer : internal pointer to next present u32 : internal shifter for curr u32 bitmap, b0 set == arg present : vendor namespace definitions : beginning of the next namespace's data : internal; reset the arg index to 0 when going to the next bitmap word

Describes the radiotap parser state. Fields prefixed with an underscore must not be used by users of the parser, only by the parser internally.
