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.
