I discovered a curious problem while trying to set up some firewalls. I do not receive multicast packets through 802.1q (vlan tagging) unless I'm doing a tcpdump on the interface. My first thought was that this was promiscuous mode-related, but I tried calling ifpromisc() from if_up() on sys/net/if.c and that didn't help. I tried to find out what else was different when this was done through bpf, but aside a bpf flag I couldn't find anything. Anyone has any clues or insights? -- Daniel C.
