Ethernet Bridge Learning.
Populate the mac table with entries mapping the packet's source mac + bridge domain ID to the input sw_if_index.
Note that learning and forwarding are separate graph nodes. This means that for a set of packets, all learning is performed first, then all nodes are forwarded. The forwarding is done based on the end-state of the mac table, instead of the state after each packet. Thus the forwarding results could differ in certain cases (mac move tests), but this not expected to cause problems in real-world networks. It is much simpler to separate learning and forwarding into separate nodes.
