MEMBERS
_rtheader
- pointer to the radiotap header we are walking through
_vns
- vendor namespace definitions
current_namespace
- pointer to the current namespace definition (or internally NULL if the current namespace is unknown)
_arg
- next argument pointer
_next_ns_data
- beginning of the next namespace's data
_next_bitmap
- internal pointer to next present u32
this_arg
- 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
this_arg_index
- index of current arg, valid after each successful call to ieee80211_radiotap_iterator_next
this_arg_size
- length of the current arg, for convenience
is_radiotap_ns
- indicates whether the current namespace is the default radiotap namespace or not
_max_length
- length of radiotap header in cpu byte ordering
_arg_index
- next argument index
_bitmap_shifter
- internal shifter for curr u32 bitmap, b0 set == arg present
_reset_on_ext
- internal; reset the arg index to 0 when going to the next bitmap word
DESCRIPTION
Describes the radiotap parser state. Fields prefixed with an underscore must not be used by users of the parser, only by the parser internally.
