+Subject: [PATCH] brcmfmac: respect hidden_ssid for AP interfaces
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This was succesfully tested with 4366B1. A small workaround is needed
+for the main interface otherwise it would stuck at the hidden state.
