50 * to call directly into bridgeif code and on top of that, directly call into
51 * the selected forwarding port's 'linkoutput' function.
52 * This means that the bridgeif input/output path is protected from concurrent access
53 * but as well, *all* bridge port netif's drivers must correctly handle concurrent access!
54 * == 0: get into tcpip_thread for every input packet (no multithreading)
55 * ATTENTION: as ==0 relies on tcpip.h, the default depends on NO_SYS setting
