+From 1b26807938815d0b0b266caf31d8ef0019607e64 Mon Sep 17 00:00:00 2001
+From: David Bauer <mail@david-bauer.net>
+Date: Mon, 27 Sep 2021 15:41:48 +0200
+Subject: [PATCH] WNM: allow specifying dialog-token
+
+This commit adds the ability to specify the dialog token of a WNM BSS
+Transition request frame via the hostapd control socket.
+
+FOr this, the new 'dialog_token' option can be used. It accepts values
+as a 8 bit unsigned integer. If not specified, the dialog token is set
+to 1 like before.
