How to revert a feature in hook_update programatically? [duplicate]

Question

I've created a feature to update a menu. Then in my deploy module, I did this:

function phoenix_deploy_update_7106() {
  $feature_list = array(
    'campus_dropdown',
  );
  features_revert($feature_list);
}

but then running drush updb -y on the staging site, doesn't enable my new menu items.

Have I gotten the commands right to revert the feature?
