rte_port_r...rag_params(3)

💖 NAME 💖

rte_port_ring_reader_frag_params — bestie, this is a struct page, and it's living in the Library Functions Manual section of the man pages (that's the manual name, it's giving section 3 energy ✨).

It's a lil' data structure that holds the params for a ring_reader_ipv4_frag port. Basically the setting sheet you hand over so your ring reader can do IP fragmentation. 🦋

🎀 Field Documentation 🎀

struct rte_ring* ring

The underlying single consumer ring that has to be pre-initialized. Like, pre-initialized. Do not come to this struct with an un-initialized ring, bestie, it's not that kind of party 🙈.

Definition at line 37 of file rte_port_frag.h.

---

uint32_t mtu

Maximum Transfer Unit (MTU). It's the maximum IP packet size, measured in bytes. 📏

Definition at line 40 of file rte_port_frag.h.

---

uint32_t metadata_size

Size of the application dependent meta-data that gets stored per each input packet. And here's the part that matters: that meta-data has to be copied to each of the fragments originating from the same input IP datagram. So every fragment gets its own copy, no sharing, no cap 🫶.

Definition at line 45 of file rte_port_frag.h.

---

struct rte_mempool* pool_direct

A pre-initialized buffer pool used for allocating the direct buffers for the output fragments. ✨

Definition at line 49 of file rte_port_frag.h.

---

struct rte_mempool* pool_indirect

A pre-initialized buffer pool used for allocating the indirect buffers for the output fragments. 🦋

Definition at line 53 of file rte_port_frag.h.
