In supported_vht_mcs_rate_nss1, the rate for MCS9 & VHT20 is defined as {780, 867}, this does not align with firmware's definition and therefore fails the verification in ath10k_mac_get_rate_flags_vht(): invalid vht params rate 960 100kbps nss 1 mcs 9 Change it to {865, 960} to align with firmware, so this issue could be fixed. Since ath10k_hw_params::supports_peer_stats_info is enabled only for QCA6174, this change does not affect other chips.
