After some testing and more studing about openwrt and switches it seems that
those configuration to make vlan woeking are veri specificar and changing a
single comma or version make them not woring anymore... those configuration
depends also a lot from the switch chip and the board setup, and making the
things worser come the fact that are unreliable...
After all this i think that 802.1ad is the right and at moment unic solution
to the problem...
