link aggregation plus active-backup

[d tbsky]

Hi:
     I have 2 server connected with a two port 10g nic, and and one
port gigabit nic. (total three ports).

     I want to do lacp with the two 10g ports. but since the ports
come from the same nic, I want to use the gigabit nic as failover
backup.

   can I make  lacp team0 with the two 10g port, then make
active-backup team1 with team0 and gigabit nic?  I wonder if this kind
of setup is doable and stable.

     thanks a lot for your help!!
