+##### Fast Session Transfer (FST) support #####################################
+#
+# The options in this section are only available when the build configuration
+# option CONFIG_FST is set while compiling hostapd. They allow this interface
+# to be a part of FST setup.
+#
+# FST is the transfer of a session from a channel to another channel, in the
+# same or different frequency bands.
+#
+# For detals, see IEEE Std 802.11ad-2012.
+
+# Identifier of an FST Group the interface belongs to.
+#fst_group_id=bond0
+
+# Interface priority within the FST Group.
+# Announcing a higher priority for an interface means declaring it more
+# preferable for FST switch.
+# fst_priority is in 1..255 range with 1 being the lowest priority.
+#fst_priority=100
+
+# Default LLT value for this interface in milliseconds. The value used in case
+# no value provided during session setup. Default is 50 ms.
+# fst_llt is in 1..4294967 range (due to spec limitation, see 10.32.2.2
+# Transitioning between states).
