Update the reading of the Tx timestamp to account for a hardware issue on how the fields and interrupt are cleared. The "seconds" portion of the timestamp should be read first, followed by the "nanoseconds" portion. Reading the "nanoseconds" portion should clear the timestamp data and the interrupt. Because of an issue with the hardware this order is reversed and reading the "seconds" portion actually clears the timestamp. The code currently follows this workaround, but to guard against future versions where this is fixed add a field to the version data to indicate if the workaround is required or not.
