I can only quote jpirko's workds from the link above:

    Do not use tlb or alb in bridge, never! It does not work, that's it. The reason
    is it mangles source macs in xmit frames and arps. When it is possible, just
    use mode 4 (lacp). That should be always possible because all enterprise
    switches support that. Generally, for 99% of use cases, you *should* use mode
    4. There is no reason to use other modes.
