This value manages rows in a PPPoE reverse-packet filter table, supporting only createAndGo, to add and activate a new filter row, and destroy, to remove one; reading this object always returns active(1) regardless of how the row was created. Administrators use it to add or remove filtering rules that control reverse (server-to-client) PPPoE packet handling for a given entry. For example, setting this to createAndGo(4) would establish a new reverse-packet filter entry, which a subsequent GET would then simply report as active(1).
