ESP01 not connecting when PMF (Protected Management Frames) enforced by AP

[SerePes]

Protected Management Frames (PMF) is a standard(802.11w) defined by WiFi Alliance to enhance WiFi connection safety. It provides unicast and multicast management actions and frames a secure method with WPA2/WPA3, which can improve packet privacy protection. Workaround is switching the protection off at WIFI AP. To support this protection following simple patch can be applied. I tested it on my mini and works fine.

Thank you for the discovery. We'll try it out and put it to the next version of FW.

As it was merged, I think this issue can be closed now.

i disabled "Management Protection" as this is how it's called in Mikrotik and it still can't connect, however i didn't apply you patch
