I'll try to do tests on my side.

(can you send me your patches directly to my email ?)

yes, the best effort with 1432 
but in a Gigabit scenario this cannot produce WITHOUT encryption a 
60% degradation... (i'm speaking about BEST results) 

I've written the patch but i will not distribute it until i 
find a valid motivation to use vxlan/gre instead of openvpn/VLAN 

I'm working on a openvpn solution for resolving the problem 
all automatic with mesh support
