[rbridge] Ingress Rbridge address and BCN

[Silvano Gai]

If the congestion is detected in the core of the TRILL network, how do
you signal back to the source host if you don't know which is the
ingresss RBridge? 

You cannot look-up the inner MAC address, because in the core of the
network you don't keep the inner MAC addresses in the table. Correct?

This is a clear reason while you need the ingress RBridge address.
