Hi , I am new to VPP. I request,if any kind hearted soul can help me understand,the boilerplate code in Node.c of a plugin. I want to understand the buffer / frame / next handling of frame/next handling of node/prefetch code ,that is under both whileS() as below.
If you can point me to any URL or any PDF/DOC,that will help me a lot in understanding. while (n_left_from > 0) { u32 n_left_to_next; vlib_get_next_frame (vm, node, next_index, to_next, n_left_to_next); while (n_left_from > 0 && n_left_to_next > 0) { ..... ... } If you can point me to any URL or any PDF/DOC,that will help me a lot in understanding.
