It is passed through from the driver.  It should be the exact same data
that the driver returns to the supplicant when parsing the scan results
through the .get_scan_results or .get_scan_results2 hooks.

It shouldn't ever be generated in the supplicant, from a quick look at
all the drivers, the IEs get copied directly into the struct
wpa_scan_res that the supplicant uses internally.

What capabilities are you looking for?  Are you talking about the AP
capabilities (privacy, qos, short slot, etc) or something else?
