Calculate the protection method to use if the given MPDU is added to the current DL MU PPDU (represented by the given TX parameters).
If the computed protection method is the same as the current one, a null pointer is returned. Otherwise, the computed protection method is returned. The TX width of the PPDU containing the MU-RTS is the same as the DL MU PPDU being protected. Each non-AP station is solicited to transmit a CTS occupying a bandwidth equal to the minimum between the TX width of the DL MU PPDU and the maximum channel width supported by the non-AP station.

txParams | the TX parameters describing the current DL MU PPDU |
