Abstract: A method of conditioning payload data includes providing a processor and receiving a packet comprising payload data, a first error code, and a second error code. The method also includes computing, using the processor, a first recalculated error code and determining a difference between the first error code and the first recalculated error code. The method further includes modifying the payload data in response to determining the difference.
