+Subject: [PATCH 135/703] brcmfmac: Re-enable firmware roaming support
+
+As of 4.18, a firmware that implements the update_connect_params
+method but doesn't claim to support roaming causes an error. We
+disabled firmware roaming in 4.4 [1] because it appeared to
+prevent disconnects, but let's try with the current firmware to see
+if things have improved.
