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