+Subject: [PATCH 7/7] hv_netvsc: Fix a network regression after ifdown/ifup
+
+Recently people reported the NIC stops working after
+"ifdown eth0; ifup eth0". It turns out in this case the TX queues are not
+enabled, after the refactoring of the common detach logic: when the NIC
+has sub-channels, usually we enable all the TX queues after all
+sub-channels are set up: see rndis_set_subchannel() ->
+netif_device_attach(), but in the case of "ifdown eth0; ifup eth0" where
+the number of channels doesn't change, we also must make sure the TX queues
+are enabled. The patch fixes the regression.
