      Short answer: No. Teaming means they look, to applications
    and the outside world, like a single adapter with the aggregated
    bandwidth.
      If the adapters go to different VLANs, you have a multi-homed box.
    If the VLANs have overlapping address spaces, you've got a really
    interesting mess on your hands, and if they don't then you can't
    usefully give the same (teamed) address to multiple adapters.
