Unsolicited broadcast probe response tranmission is used for in-band
discovery in 6GHz band (IEEE P802.11ax/D6.0 26.17.2.3.2, AP behavior for
fast passive scanning).
The new attribute, NL80211_ATTR_UNSOL_BCAST_PROBE_RESP, is nested which
supports following parameters:
(1) NL80211_UNSOL_BCAST_PROBE_RESP_INT - Packet interval
(2) NL80211_UNSOL_BCAST_PROBE_RESP_TMPL - Template data
