+Subject: [PATCH] brcmfmac: restore stopping netdev queue when bus clogs up
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When the host-interface bus has hard time handling transmit packets
+it informs higher layer about this and it would stop the netdev
+queue when needed. However, since commit 9cd18359d31e ("brcmfmac:
+Make FWS queueing configurable.") this was broken. With this patch
+the behaviour is restored.
+
+Cc: stable@vger.kernel.org # v4.5, v4.6, v4.7
+Fixes: 9cd18359d31e ("brcmfmac: Make FWS queueing configurable.")
