Fix the calculation according to the phydm_rxsc_2_bw() function from the official drivers. After: tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2 rx bitrate: 390.0 MBit/s VHT-MCS 9 80MHz VHT-NSS 1 It also works correctly with the AP configured for 20 MHz and 40 MHz. Tested with RTL8822CE.
