Hello Andrew,

The current driver implementation uses only a single FDB for the switch,
so  it is not possible configure multiple flooding domains to accommodate
ports partitioning.

Ah, O.K. Rather than break somebodies network by wrongly flooding, it
would be better to return -EOPNOTSUPP when the requirement for the
second FDB is met. The offload to hardware will then not happen, and
the software bridge will do all the work.

Thank you for your suggestion. I will add to the TODO list in v6.

Razvan
