Why do you want to use lwIP. Of course it's possible to do that, but have you 
thought about using Linux with RT patch? Would that not be enough to reach your 
requited realtime timing?

With your approach, I guess you will need to give lwIP exclusive access to the 
petrol interface.

I really can't help you much there. If the network interface is for use 
exclusively to lwIP, I guess the netif driver can be reused. But you'll need to 
port lwIP to Xenomai (if that hasn't been done yet).
