The ratecode field given by firmware in the tx stats gives the details of NSS and MCS, if the preamble specifies that it is HT/VHT. In case of OFDM/CCK, as specified by the preamble, the ratecode indicates the legacy rate instead of NSS/MCS data. For OFDM/CCK cases, the NSS should always be 1, i.e. 1x1 mode for 11g and 11b. Currently the legacy rate is misinterpreted as NSS & MCS, leading to incorrect updation of tx stats corresponding to NSS, which is displayed in the tx stats via debugfs. Fix the nss value to 1 for 11b and 11g modes by checking the preamble indication in the ratecode provided by the firmware.
