Configure DHCP Snooping

@bonnietwin Thanks! I think the addon may be suitable… It will be necessary to further study this issue… It would be great if it was described in the wiki or implemented in a ipfire…

@trash-trash yes, this is the switch’s job, and, for example, mikrotik knows how to do it, and devices that don’t know how to do it, at least they only make mentions in the event log.
