okay bestie, pull up a chair, we're talking about rte_mbuf_ext_shared_info — it's a struct from the DPDK library, and yes it lives in section 3 of the manual (library functions, iykyk). it's literally the shared data that chills at the end of an external buffer. tiny struct, big main character energy. let's get into it 🌸
