http://netbsd.gw.com/cgi-bin/man-cgi?ieee80211_radiotap+9+NetBSD-current states:

     IEEE80211_RADIOTAP_EXT
             This bit is reserved for any future extensions to the radiotap
             structure.  A driver sets IEEE80211_RADIOTAP_EXT to extend the
             it_present bitmap by another 64 bits.  The bitmap can be extended
             by multiples of 32 bits to 96, 128, 160 bits or longer, by set-
             ting IEEE80211_RADIOTAP_EXT in the extensions.  The bitmap ends
             at the first extension field where IEEE80211_RADIOTAP_EXT is not
             set.


The sentence "A driver sets IEEE80211_RADIOTAP_EXT to extend the it_present bitmap by another 64 bits". this is wrong. it should say "32 bits" instead.
