+Subject: [PATCH] brcmfmac: support removing AP interfaces with
+ "interface_remove"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+New firmwares (e.g. 10.10.69.36 for BCM4366) support "interface_remove"
+for removing interfaces. Try to use this method on cfg80211 request. In
+case of older firmwares (e.g. 7.35.177.56 for BCM43602 as I tested) this
+will just result in firmware rejecting command and this won't change any
+behavior.
