If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
will be performed and stored in NVS. Normally, only partial calibration will be performed.
If this option is disabled, full calibration will be performed.
If calibration data is not found, full calibration will be performed and stored in NVS. Normally,
only partial calibration will be performed. If this option is disabled, full calibration will be performed.
Full calibration needs 170 - 180ms.
Partial calibration needs 35 - 40ms.
No calibration needs 3.260 - 3.264ms.
If it's easy that your board calibrate bad data, choose 'n'.
Two cases for example, you should choose 'n':
