In order to understand where a broadcast packet is coming from and use this information to detect not yet announced clients, this patch modifies the interface_rx() function by passing a new argument: the orig node corresponding to the node that originated the received packet (if known). This new argument if not NULL for broadcast packets only (other packets does not have source field). Signed-off-by: Antonio Quartulli <ordex@autistici.org>
