usb device to ether is not identification in 64bit Windows OS

[Lipengcheng]

Hi,
kernel version：4.8.0
file:Documentation / usb / linux.inf
problem:PC windows is 32bit OS, using Ethernet gadget driver, it can be correct identification. But PC windows is 64bit OS, while modifying linux.inf file LinuxDevice parameters, it can not correct identification, the serial port can be printed correctly:g_ether gadget: high-speed config # 2: RNDIS. I suspect that the linux.inf files are not mismatch 64bit windows OS.

Best regards,
Pengcheng Li

Given that everyone here does not use Windows at all, you are going to
be on your own here, sorry.  If you do come up with an updated .inf
file, we will be glad to take a patch.

good luck,

Hi,
	In windows official web, download a new linux.inf file, and add our hisilicon usb id. Now it can be used correct identification in PC windows 64bit OS. At the same time, it can also be used correctly in PC windows 32bit OS.
windows official web: https://msdn.microsoft.com/zh-cn/windows/hardware/drivers/network/remote-ndis-inf-template
the new file(add hisilicon usb id):
