Dradiotap-headers.rst4 How to use radiotap headers
7 Pointer to the radiotap include file
62 the first byte of the radiotap header. The absolute alignment of that first
63 byte isn't defined. So even if the whole radiotap header is starting at, eg,
64 address 0x00000003, still the first byte of the radiotap header is treated as
68 entities in the fixed radiotap header or the argument region means that you
81 Example valid radiotap header
86 0x00, 0x00, // <-- radiotap version + pad byte
87 0x0b, 0x00, // <- radiotap header length

20 radiotap headers and used to control injection:
70 The injection code can also skip all other currently defined radiotap fields
71 facilitating replay of captured radiotap headers directly.
73 Here is an example valid radiotap header defining some parameters::
