Subject: [PATCH 315/454] usb: gadget ethernet: Re-enable Jumbo frames.
Commit <eea52743eb5654ec6f52b0e8b4aefec952543697> upstream
Fixes: <b3e3893e1253> ("net: use core MTU range checking")
which patched only one of two functions used to setup the
USB Gadget Ethernet driver, causing a serious performance
regression in the ability to increase mtu size above 1500.
