Christian S.J. Peron 6f75ef188b Slightly re-worked bpf(4) code associated with bridging: if we have a ... destination interface as a member of our bridge or this is a unicast packet, push it through the bpf(4) machinery. For broadcast or multicast packets, don't bother with the bpf(4) because it will be re-injected into ether_input. We do this before we pass the packets through the pfil(9) framework, as it is possible that pfil(9) will drop the packet or possibly modify it, making it very difficult to debug firewall issues on the bridge. Further, implemented IFF_MONITOR for bridge interfaces. This does much the same thing that it does for regular network interfaces: it pushes the packet to any bpf(4) peers and then returns. This bypasses all of the bridge machinery, saving mutex acquisitions, list traversals, and other operations performed by the bridging code. This change to the bridging code is useful in situations where individuals use a bridge to multiplex RX/TX signals from two interfaces, as is required by some network taps for de-multiplexing links and transmitting the RX/TX signals out through two separate interfaces. This behaviour is quite common for network taps monitoring links, especially for certain manufacturers. Reviewed by: thompsa MFC after: 1 month Sponsored by: Seccuris Labs		2006-03-03 05:58:18 +00:00
