Thanks for your suggestion. After this single patch for patch v4, we fixed issues of host mlme and WPA3 for STA mode from our QA and customer. We also completed host mlme and WPA3 for AP mode.
For patch v5, we will create a cover letter with a series of patches which can fully support host mlme and WPA3 for STA and AP modes.
