4 | Subject: [PATCH] usb gadget: fix ethernet link reports to ethtool | ||
5 | |||
6 | The g_ether USB gadget driver currently decides whether or not there's a | ||
7 | link to report back for eth_get_link based on if the USB link speed is | ||
8 | set. The USB gadget speed is however often set even before the device is | ||
9 | enumerated. It seems more sensible to only report a "link" if we're | ||
10 | actually connected to a host that wants to talk to us. The patch below | ||
11 | does this for me - tested with the PXA27x UDC driver. | ||
