No... this patch doesn't introduce an nl80211 event. It introduces a
feature flag, but I'm arguing it's useless.

Look - what's the difference that userspace would do based on this
flag? Clearly, setting the flag in the driver has no effect on kernel
code whatsoever, so your "is not able to be brought up" makes no sense.

Perhaps it'll become clearer once you post the wpa_supplicant code, but
you should still coherently explain in the commit message why this is
necessary. So far, I don't see it, since no kernel code ever depends on
this flag.
