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. Signed-off-by: Ash Hughes <ashley.hughes@blueyonder.co.uk> SVN-Revision: 28267
