Firmware builds the AP MLD partner profile from the hw_link_id passed in the vdev start parameters. However, hw_link_id is not always the same as the logical per-MLD ieee_link_id, since ieee_link_id is assigned per MLD and not per pdev. This matters in mixed MLO and SLO setups. For example: MLD 1 - 5 GHz + 6 GHz (2-link MLO): ieee_link_id 0 and 1 MLD 2 - 6 GHz only (1-link SLO): ieee_link_id 0 MLD 3 - 5 GHz only (1-link SLO): ieee_link_id 0 The same physical 6 GHz radio can use ieee_link_id 1 for one MLD and ieee_link_id 0 for another. Pass the correct ieee_link_id to firmware so it can build accurate per-STA profile elements. Add ieee_link_id to wmi_vdev_start_mlo_params for the self link and to wmi_partner_link_info for each partner link. Populate these fields in ath12k_mac_mlo_get_vdev_args() from the corresponding vdev link_id before encoding the WMI command. Introduce two new flags in ML params to indicate to firmware when the new fields are valid: ATH12K_WMI_FLAG_MLO_IEEE_LINK_IDX_VALID BIT(18) for the self link ATH12K_WMI_FLAG_MLO_IEEE_LINK_IDX_VALID_PARTNER BIT(19) for partner links Firmware parses ieee_link_id only when the matching flag is set. Also fix the debug message by using correct format specifiers and host-endian values instead of __le32 values.
