nix-vector routing and tap bridge

[efak]

Hi,

I modified tap-csma.cc to use nix-vector routing and I keep getting SIGSEGV signal. I tried debugging with but only got the message below. Can anyone point me to why I am getting the error? Code attached.

  

Thread 1 "tap-csma_my" received signal SIGSEGV, Segmentation fault.
