I guess the reason you don't use the nl80211 enum here is that the
device doesn't care since the beacon is built by hostapd/mac80211 and
entirely transparent to the device?

Any particular reason for not just inlining the few code lines?
However, what's this used for? Didn't we discuss this before and decide
that there's no clear way to implement probe response offloading given
the possibility that WPS, P2P and similar protocols that use probe
request/response handshaking could be in use?
