Assuming one PANU wishes to send IP traffic to another PANU. When this BNEP frame encapsulating the ARP request arrives at the GN, is it broadcast on all bridge ports? Also does the bridge implimentation result in one broadcast per "port" i.e. instead of one baseband layer broadcast (i.e. LT_ADDR = 000), we will have as many broadcasts as the number of connected PANUs (i.e. one per port)? I hope I'm not sounding too confused. Thanks for your explaination.
