+Subject: [PATCH] usb gadget: fix ethernet link reports to ethtool
+
+The g_ether USB gadget driver currently decides whether or not there's a
+link to report back for eth_get_link based on if the USB link speed is
+set. The USB gadget speed is however often set even before the device is
+enumerated. It seems more sensible to only report a "link" if we're
+actually connected to a host that wants to talk to us. The patch below
+does this for me - tested with the PXA27x UDC driver.
