37 *
38 * In IEEE 802.15.4 packets, all fields are little endian. And
39 * Each byte is transmitted least significant bit first (reflected
40 * bit ordering).
41 *------------------------------------------------------------
42 *
43 * Most IEEE 802.15.4 Packets have the following format:
44 * | FCF |Seq No| Addressing | Data | FCS |
45 * |2 bytes|1 byte|0 to 20 bytes|Length-(Overhead) bytes|2/4 Bytes|
46 *------------------------------------------------------------
47 *
48 * Multipurpose frame packets have the following format:
49 * | FCF | Seq No | Addressing | Data | FCS |
50 * |1/2 bytes|0/1 bytes|0 to 20 bytes|Length-(Overhead) bytes|2 bytes|
51 *------------------------------------------------------------
52 *
53 * CRC16 is calculated using the x^16 + x^12 + x^5 + 1 polynomial
54 * as specified by ITU-T, and is calculated over the IEEE 802.15.4
55 * packet (excluding the FCS) as transmitted over the air. Note,
56 * that because the least significant bits are transmitted first, this
57 * will require reversing the bit-order in each byte. Also, unlike
58 * most CRC algorithms, IEEE 802.15.4 uses an initial and final value
59 * of 0x0000, instead of 0xffff (which is used by the ITU-T).
60 *
61 * For a 4-byte FCS, CRC32 is calculated using the ITU-T CRC32.
62 *
63 * (Fun fact: the reference to "a 32-bit CRC equivalent to ANSI X3.66-1979"
64 * in IEEE Std 802.15.4-2015 nonwithstanding, ANSI X3.66-1979 does not
65 * describe any 32-bit CRC, only a 16-bit CRC from ITU-T V.41. ITU-T
66 * V.42 describes both a 16-bit and 32-bit CRC; all the 16-bit CRCs
67 * floating around seem to use the same generator polynomial,
68 * x^16 + x^12 + x^5 + 1, but have different initial conditions and
69 * no-error final remainder; the 32-bit CRC from V.42 and the one
70 * described in IEEE Std 802.15.4-2015 also use the same generator
71 * polynomial.)
72 *------------------------------------------------------------
73 *
74 * This dissector supports both link-layer IEEE 802.15.4 captures
75 * and IEEE 802.15.4 packets encapsulated within other layers.
76 * Additionally, support has been provided for 16-bit and 32-bit
77 * FCS, as well as for frames with no FCS but with a 16-bit
78 * ChipCon/Texas Instruments CC24xx-style metadata field.
