* The value of the parameter is compared against the OBSS RSSI in dB.
* It is a 8-bit value whose

* For example, if the parameter value is 0xF5, the target will
* allow spatial reuse if the RSSI detected from other BSS

* Similarly, if the parameter value is 80, the target will

* Similarly, if the parameter value is 0x0A, the target will
