+Subject: [PATCH 346/374] 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.
