Assume in case of STA + STA, where STA1 is on 2G band and STA2 is on 5G band. While switching STA1 to STA2, hdd_reg_set_band issue disconnect, in order to change band (say 2G to 5G) and start processing roam scan offload request to make sure roaming gets enable on only one STA at a time. eWNI_SME_DISASSOC_REQ and eWNI_SME_ROAM_SCAN_OFFLOAD_REQ msg get posted to lim back to back through a single thread. HOST starts processing DISASSOC_REQ first and waits for tx_completion ACK for disassoc frame. Ideally, Host should process eWNI_SME_ROAM_SCAN_OFFLOAD_REQ before getting ACK for disassoc frame. In case if DUT immediately gets disassoc ACK, DUT complete disassoc req and then gets chance to process SCAN_OFFLOAD req. Once DUT enters into Disconnection state, HOST never sends RSO stop command to FW and leads to assert in fw. Fix is to synchronize eWNI_SME_DISASSOC_REQ and eWNI_SME_ROAM_SCAN_OFFLOAD_REQ command to make sure RSO stop gets process first followed by Disconnection/deauth.
