Hello, I am trying to modify how OVS pops MPLS labels. I have two questions about pop_mpls implementation:
1) What is the difference between the three functions: datapath/actions.c: pop_mpls lib/packets.c: pop_mpls lib/flow.c: flow_pop_mpls Specifically, when is each of them called? and why is there a flow_pop_mpls and pop_mpls? When I commented the first two functions, pop_mpls action works as usual; when I commented the three functions, nothing was popped. 2) During executing pop_mpls (or flow_pop_mpls), can I output the packet to a particular port? Regards, Khaled
