generic: jumbo frames support for rtl8366s
This patch adds the option to enable jumbo frames on the rtl8366s
switch. This is almost exactly the same as the first patch at
https://dev.openwrt.org/ticket/7977 and it has been requested
in a comment there.
I have tested this and it successfully allows devices on the switch
using jumbo frames to communicate.
