I currently have code loaded and running on the IXP1200 as follows: ME 0-1 are running the FastIngress code (1 gigabit port), ME 2-3-4 are running processing code (packet counting of various sorts), ME 5 is running FastEgress code. Now, I need to be able to send packets from one microengine to another preferably without involving the StrongARM. I'm thinking that the ME-ME ring may provide me with what I need, but I can't see how packets are enqueued and dequeued. The DL_MESink macro seems to enqueue a packet, but there is no corresponding code to dequeue a packet. My understanding so far is that the packet is dequeued by the egress code. Can the ME-ME ring(s) be used (adapted) for passing packets between microengines, or do I need to write my own queue/dequeue code? Thanks, Chris
