It should contain IFF_PROMISC when set by this bit of code: David, it is not a bug, but more a FAQ. Newer libpcap uses the PACKET_ADD_MEMBERSHIP to PACKET_MR_PROMISC socket options. They have an reference count instead of the old broken non ref counted bit. packet calls dev_set_promiscuity directly. Turning on/off the flag virtually when the reference count is >0 would break compatibility so it is not done. -Andi - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
