Interesting, the checksum looks like a standard LFSR but uses addition instead of XOR. 1) Seed checkum with initial_value 2) Add a data uint sized to the chec

Interesting, the checksum looks like a standard LFSR but uses addition instead of XOR. 1) Seed checkum with initial_value 2) Add a data uint sized to the checksum 3) Shift up by 1 bit while feeding back the MSB to the LSB. 4) GOTO 2 until you have consume all the data. Not sure why you would process with usual addition instead of GF2 addition.
