The case bond -> vlan -> netxen was intentionally dropped as it leads to
many new issues, if that is what you are referring to. The case vlan ->
netxen still works, since the address of orig_dev is unconditionally
programmed if the original dev is a netxen. The problem was with a bond
acting on a vlan which is configured on a netxen because we would have
to keep track of which bonding master the programmed addresses belong to.
