Subject[PATCH net-next] net: dsa: Never offload FDB entries on standalone ports
Date
If a port joins a bridge that it can't offload, it will fallback to
standalone mode and software bridging. In this case, we never want to
offload any FDB entries to hardware either.

Fixes: c26933639b54 ("net: dsa: request drivers to perform FDB isolation")
