What's the reasoning behind:

1. Backporting this patch?

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.

What issue is that?  Where was it reported?

2. A partial backport of this patch?

The other part does not actually fix anything.

Then why is it not ok to just take the whole thing?

When backporting not-identical-patches, something almost always goes
wrong, so we prefer to take the original commit when ever possible.

thanks,

greg k-h
