I'm using FreeBSD 4.5 on a Toshiba Tecra 8100 with a 3COM 3C589 PCMCIA LAN card. The problem I am having is that when broadcast packets are sent I see them twice in tcpdump running on the same machine, with a split second difference in the timestamp for each packet. I know the broadcast packet is actually only being sent once onto the network as when I run tcpdump on another machine it sees the packet only once. Therefore it would appear that the broadcast packet is being looped back up through the TCP/IP stack. Also if I try this on another machine using Intel cards (fxp0) the problem goes away, so it would seem to point to the PCMCIA card or driver as the source of the problem. If this problem has been documented before, my apologies for dragging up old issues and would someone point me to the relevant document; else any one with any ideas?
