Here were the test cases
For test case 10153_1:  The test bed AP beacons with no security.  The
test case requires the STAUT to connect with WPA2-PSK only.  Because
of the mismatch of security protocols, the connection will fail.

For test case 10165_1: The test bed AP advertises at WPA2-Personal
only.  The test case requires the STAUT to connect with WPA3-Personal.
Because of the mismatch of security protocols, the connection will
also fail.

I got the PDFs of the test cases I can share offlist as well.  10153_1
looks like it would not connect, but apparently hung up on the setting
the STAUT to WPA2-PSK only.  So it looks like I need a way to restrict
IWD from using other security types for these tests.  If you have any
suggestions on a good way to do this, let me know.

Thanks
