✨ rte_port_frag.h — the manual page, but make it cute ✨

okay bestie, grab your iced coffee because we're reading a Library Functions Manual page and it's giving "kernel-adjacent but make it fashion". The page you're holding is rte_port_frag.h(3), and no, I will not be normal about it 💅

🌸 NAME 🌸

rte_port_frag.h — that's literally the whole name, she's lowkey mysterious like that 🫶

🌈 SYNOPSIS 🌈

#include <stdint.h>
#include 'rte_port.h'

🎀 Data Structures

  • struct rte_port_ring_reader_frag_params — yes queen, she's the struct

🦋 Variables

  • struct rte_port_in_ops rte_port_ring_reader_ipv4_frag_ops
  • struct rte_port_in_ops rte_port_ring_reader_ipv6_frag_ops

💖 Detailed Description 💖

RTE Port for IPv4 Fragmentation

so the tea is this, bestie: this port is built on top of a pre-initialized single consumer rte_ring ✨

and the reason why? to minimize the amount of packets stored in the ring at any given time, the IP fragmentation functionality is executed on ring read operation — which is exactly why this port is implemented as an input port. ikyk 😌

and if you wanna write to that same ring? a regular ring_writer port can be created to write to the same ring. two ports, one ring, no drama 🫶

now the packets — let's break it down, no cap:

  • the packets written to the ring are either complete IP datagrams or jumbo frames (i.e. IP packets with length bigger than the provided MTU value) 🐘
  • the packets read from the ring are all non-jumbo frames 👑
  • the complete IP datagrams written to the ring are not changed — she's perfect, leave her alone 🙅
  • the jumbo frames are fragmented into several IP packets with length less or equal to MTU ✂️✨
