[ Upstream commit 52db16ec5bae7bd027804265b968259d1a6c3970 ]
In supported_vht_mcs_rate_nss2, the rate for MCS9 & VHT20 is defined as {1560, 1733}, this does not align with firmware's definition and therefore fails the verification in ath10k_mac_get_rate_flags_vht():
invalid vht params rate 1730 100kbps nss 2 mcs 9
and:
invalid vht params rate 1920 100kbps nss 2 mcs 9
Change it to {1730, 1920} to align with firmware to fix the issue.
Since ath10k_hw_params::supports_peer_stats_info is enabled only for QCA6174, this change does not affect other chips.
Tested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00309-QCARMSWPZ-1
