There's a 32-bit CRC function:

	; lookman crc
	man 2 flate # flate(2)
	; sig mkcrctab blockcrc
		ulong *mkcrctab(ulong poly)
		ulong blockcrc(ulong *tab, ulong crc, void *buf, int n)

but it's also possible that some command has a 16-bit CRC function
within it.

Is there any particular advantage to using a 16-bit (rather than
32-bit) CRC, now that 16-bit machines are rare?
