Can port_serdes be removed on the fly? Or do you require the port to be shutdown etc?

It can be removed on the fly. It just removes the software object. The logic is introduced because the port serdes object has all attributes as create only and since multiple attributes need to be set which the current set attribute doesn't support, we have this logic of deleting the existing object and recreating it.
