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.
