WebAug 5, 2024 · bmv2 uses standard crc polynomials, so you should be able to use a Python package such as crcmod to compute the hash in a way which is consistent with the bmv2 implementation. The easiest way is probably to use the crc16_custom hash in P4 instead of crc16 and configure the polynomial with the set_crc16_parameters runtime_CLI … WebMar 29, 2014 · When using a table, your 0x06 is exclusive-ored with the CRC (which end depends on whether your polynomial is reflected or not), and then that byte is used to lookup a 16-bit value in a table. The CRC is shifted by eight (direction dependent on reflection), and then exclusive-ored with the table value. That is then repeated for 0x17. – Mark ...
