generic: jumbo frames support for rtl8366s

Browse Source 
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.
