It is suggestion provided by EEPROM, so driver is free to fallow it. If
you will force the driver not to fallow it, and it will damage your
hardware or produce some interference with radar working on 5GHz - it
will be your own responsibility.

Normally 5 GHz AP should provide Dynamic Channel Switch and Radar
Detection, which is not provided by ath9k_htc driver.
