For the issue of code style, I am not sure what you mean here.  I copied
this code from the nl80211_connect routine, which has similar processing
for a ?use MFP? parameter.  I tried to make the code I added be consistent
with this existing code.

If you explain what needs to be changed to improve the code style, I will
make the changes.

Regarding your question about a feature flag, there is already a  flag
that indicates that the driver implements the AP SME:
     * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME
Is this the type of flag you were referring to?

I am ready to respond to any follow-on comments you have for this section
of code.
