CRC6: Fixed CRC lookup table and functions
* Generated code and 256-element lookup table with pycrc
* Combined 2 crc6 functions which both have same poly 0x6f and lookup table
* Using the example file from the bug report,
$ tshark -r ~/Downloads/M1_header_crc.pcapng -V | grep "Calculated CRC"
1101 00.. = Header CRC: 0x34 [Calculated CRC 0x34]
Header and Calculated CRC are now both 0x34 (correct value)
* pycrc settings for generation:
$ python pycrc.py --reflect-in False \
--reflect-out False \
--xor-in 0 \
--xor-out 0 \
--algorithm table-driven
--width 6 \
--poly 0x2f
* To manually check 3GPP protocol header CRCs, use above command with flag
--check-hexstring=<HEADER HEX>
