Found a number of problems with the router when compiling on linux
* Expected malloc()'ed memory to be zeroed resulting in segfault
* IPC_NOWAIT in iplayer loop means incoming traffic will be delayed until outgoing traffic is received.
* When configured with two BIP interfaces, broadcast loops ensue because the broacast traffic is not correctly filtered. I think the safest thing to do here is to use the SO_BINDTODEVICE setsockopt.
