+database.
+.Pp
+The
+.Fn lib80211_alloc_regdata
+and

+and
+.Fn lib80211_regdomain_cleanup
+functions read in the regulatory database XML configuration and free it when
+finished.
+.Pp
+The
+.Fn lib80211_regdomain_findbysku
+and
+.Fn lib80211_regdomain_findbyname
+functions lookup a regulatory domain entry by SKU enum and SKU name
+respectively.
+.Pp
+The
