Standalone ports should have address learning disabled, according to
the documentation:
https://www.kernel.org/doc/html/v5.14-rc7/networking/dsa/dsa.html#bridge-layer
dsa_switch_ops on 5.10 or earlier does not have .port_bridge_flags
function so it has to be done differently.

I've identified an issue related to this.

The other part does not actually fix anything.
