I'm not sure I entirely follow what you are doing.  Here is what I think you
mean.  Please correct me if I'm wrong.  You have implemented a network
management layer that interfaces directly with can0.  All other applications
interact with can0v, which is always up.  When you know the communication
is stable you route between can0 and can0v.  Did I get that right?

So do you take can0 down/up when timeouts occur with messaging?  Is there
any kind of startup delay associated with this?  Is there any kind of
delays going to can0v?

What do you mean by the TX-timeout or restart-ms option?
