I would like to move forward and push the V2 patch series upstream 
through netdev and then start working on the configuration tools etc 
changes needed to support bonding IPoIB devices through non direct 
bonding sysfs scripts... are you OK with that?

If you agree to the push, who is doing this nowadays, is it Jeff Garzik 
or David Miller?

Roland - any other comments/concerns that you might have are very much
