When stations that support EHT capability try to connect to the AP, the AP will set phy mode to EHT after receiving the association request packet, and then send WMI_PEER_ASSOC_CMDID command to firmware, AP’s firmware will crash. This is because when the ath12k_mac_copy_sband_iftype_data() function handles EHT capability, it does not copy the EHT capability into the iftype[band][type] array according to the interface type. So, interface type should not be used as an index to get eht_cap in ath12k_mac_check_down_grade_phy_mode() function. To address this issue, use types_mask to select the eht_cap in ath12k_mac_check_down_grade_phy_mode() function. This patch affects QCN9274 and WCN7850 because they have the same issue.
