[ovs-discuss] Datapath loop

I've been studying the Open vSwitch code and I couldn't understand what the
"datapath loop" means...
I noticed the comment before the struct loop_counter declaration ("*We limit
the number of times that we pass into dp_process_received_packet() to avoid
blowing out the stack in the event that we have a loop"*) but I couldn't
figure out what the "datapath loop" means.

When this "datapath loop" happens? In which situation the
dp_process_received_packet() is called within a "loop"?
