Table 32. PMA Parameter Tuning for Optimal Performance
These are the tuned PMA parameter settings that result in optimal link performance across a temperature
sweep for each test configuration. An integer value means that the parameter is fixed, and "Firmware Default"
means that the parameter is adaptive.
