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.
