We have MPC8548CDS eval board. How to configure all the 4 tsec port to be in same subnet so that that all the 4 tsec 
ports are pingable from  externally connected devices. for example the assigned address may be:
tsec0 172.195.51.2
tsec1 172.195.51.3
tsec2 172.195.51.4
tsec3 172.195.51.5

The question might be  wrong from concept wise, but still I request to comment.
