Currently tx_params is being re-assigned with a new value and the previous setting IEEE80211_HT_MCS_TX_RX_DIFF is being overwritten. The assignment operator is incorrect, the original intent was to bit-wise or the value in. Fix this by replacing the = operator with |= instead. Kudos to Christian Lamparter for suggesting the correct fix.
