Channel Bonding and Bridging

Hello !

One of my thousands questions about Channel Bonding !

I tried to enable Channel Bonding and Bridging at the same time (the tool
brctl) but that's seems it does not work :
When I up the bonding interfaces, the linux does not bridge anymore
and
when I up the bridge group ("ifconfig bridgegroup up"), the bonding does not
work anymore !

Yet, I think that would be very useful to do the both at the same time, the
uses are obvious to me...

Any idea ?

Thank you.
