[PATCH] net: smsc95xx: Fix MTU range

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The commit f77f0aee4da4 ("net: use core MTU range checking in USB NIC
drivers") introduce a common MTU handling for usbnet. But it's missing
the necessary changes for smsc95xx. So set the MTU range accordingly.

This patch has been tested on a Raspberry Pi 3.
