FILS discovery attribute, NL80211_ATTR_FILS_DISCOVERY, is nested which
supports following parameters as given in IEEE Std 802.11ai-2016,
Annex C.3 MIB detail:
(1) NL80211_FILS_DISCOVERY_ATTR_INT_MIN - Minimum packet interval
(2) NL80211_FILS_DISCOVERY_ATTR_INT_MAX - Maximum packet interval
(3) NL80211_FILS_DISCOVERY_ATTR_TMPL - Template data
