- * crc8
- *
- * Computes a crc8 over the input data using the polynomial:
- *
- *       x^8 + x^7 +x^6 + x^4 + x^2 + 1
- *
- * The caller provides the initial value (either CRC8_INIT_VALUE
- * or the previous returned value) to allow for processing of
- * discontiguous blocks of data.  When generating the CRC the
- * caller is responsible for complementing the final return value
- * and inserting it into the byte stream.  When checking, a final
- * return value of CRC8_GOOD_VALUE indicates a valid CRC.
