generic: add NET3380 UDC support
Add a patch to backport 5185c91385d73cdf79836eb8548e4726e43ae831 from Linux 4.8 adding USB2380 support to the NET2280 driver and create an OpenWrt menu option to select it as a module. Signed-off-by: Tim Harvey <tharvey@gateworks.com>

Subject: [PATCH] usb: gadget: net2280: add USB2380 support
|
||||
|
||||
The PLX USB2380 is a PCIe version of the NET2280 and behaves more like the
|
||||
USB338x but without the USB3.0 superspeed support.
|
||||
|
||||
This was tested with g_ether, g_serial, g_mass_storage on a Gateworks
|
||||
Ventana GW2383.
