I can't reproduce this here. I am currently running v6.4-rc3 plus: wifi: rtw88: usb: silence log flooding error message I tested on a i.MX6S (not SoloX) board with Firmware 9.9.14. A "nmcli dev wifi rescan" works just fine and the link also continues to work. I verified that FW_FEATURE_SCAN_OFFLOAD is set and used in the driver, also that it's not set in Firmware 9.9.9. I also tried to put some load on the link by running iperf3, still no difference.
