This does not need to be specified twice.  While it should compile, it is unneeded duplication.  Instead, define it once _outside_ this if/else, and simply specify the ordering within the check, like so (snipped psuedo code):
```
if $cisco_vswitch_plugin == 'neutron.plugins.cisco.n1kv.n1kv_neutron_plugin.N1kvNeutronPluginV2' {
  # any other needed config, ordered if needed
  Package['neutron-plugin-ovs'] -> Class['::quickstack::neutron::plugins::cisco']
} else {
  Class['::quickstack::neutron::plugins::cisco']
}
```
