Add the following new WCNSS_qcom.ini value: "prefer_roam_score_for_candidate_selection" - choose to sort the candidates on roam score or preferred AP list send in the BTM request frame by AP. When this ini is set, host driver will modify btm_offload_config bit 7 which will be read by firmware to get this ini value. “roam_candidate_validity_timer” - roam cache entries validity timer. The candidates in the roam cache are valid only for this time value. This value is sent to firmware over the wmi command on the structure wmi_roam_offload_tlv_param "btm_disassoc_timer_threshold" - Disassociation timer threshold to wait after which the full scan for roaming can be started after the AP has sent the disassoc imminent Change-Id: I3ba5ba2182b1b6d722d9c315757332a1b3e62521 CRs-Fixed: 2369018
