rte_arp.h(3)

๐Ÿ’… rte_arp.h โ€” the manual page, but make it make sense ๐Ÿ’…

okay so bestie, welcome to rte_arp.h(3) โ€” yes, that's the DPDK one, section 3, we're in the library docs now ๐Ÿซถ this file is literally just the ARP-related defines and it's giving "small but mighty" energy fr fr.


โœจ NAME โœจ

rte_arp.h โ€” that's the name, that's the whole vibe, no cap ๐ŸŒธ


๐Ÿฆ‹ SYNOPSIS ๐Ÿฆ‹

okay so before you can even look at the ARP stuff you gotta bring your friends along, and by friends I mean these two headers, exactly like this, no substitutions:

#include <stdint.h>
#include <rte_ether.h>

๐Ÿ’œ Functions ๐Ÿ’œ

here's what's actually in here โ€” two things, and yes one of them is a struct that lowkey looks like a function in the docs but isn't, don't @ me, that's just how Doxygen woke up that day ๐Ÿ˜ญ

struct __rte_aligned (2) __rte_packed_begin rte_arp_ipv4
struct rte_mbuf * rte_net_make_rarp_packet (struct rte_mempool *mpool,
    const struct rte_ether_addr *mac)

๐ŸŽ€ Detailed Description ๐ŸŽ€

ARP-related defines โœจ that's it, that's the description, main character energy but make it concise ๐Ÿ’…

this thing is a Definition in file rte_arp.h โ€” so like, it lives there, that's its home ๐Ÿ 

๐Ÿ”ฅ Function Documentation ๐Ÿ”ฅ

๐ŸŒˆ struct __rte_aligned (2) ๐ŸŒˆ

this is the ARP header IPv4 payload ๐Ÿ‘‘ iconic, packed, aligned to 2, doing the absolute most.

here's the field-by-field breakdown, and I'm keeping every single one because every single one matters:

  • < sender hardware address ๐Ÿ˜ค
  • < sender IP address ๐Ÿ“ฎ
  • < target hardware address ๐ŸŽฏ
  • < target IP address ๐Ÿ
  • < format of hardware address ๐Ÿงพ
  • < format of protocol address ๐Ÿ“œ
  • < length of hardware address ๐Ÿ“
  • < length of protocol address ๐Ÿ“
  • < ARP opcode (command) โšก

๐Ÿงš struct rte_mbuf* rte_net_make_rarp_packet (struct rte_mempool * mpool, const struct rte_ether_addr * mac) ๐Ÿงš

Make a RARP packet based on MAC addr. ๐Ÿฆ‹ yes bestie, RARP, not ARP, we're going backwards up in here, it's reverse o'clock โช

๐Ÿ’– Parameters ๐Ÿ’–

  • mpool โ€” Pointer to the rte_mempool ๐ŸŠ that's your memory pool, that's where the packet's gonna come from
  • mac โ€” Pointer to the MAC addr ๐Ÿ“ the address we're building this whole thing around

โญ Returns โญ

  • RARP packet pointer on success ๐ŸŽ‰ or NULL on error ๐Ÿ’€

no in-between, it's giving binary success/failure realness ๐Ÿ™ˆ

okay that's the whole page, you made it, I'm so proud of you ๐Ÿฅน๐Ÿ’–


โœจ one last thing bestie โœจ this was Version 25.11.0, stamped Fri Jan 30 2026, brought to you by the DPDK girlies (and Doxygen). go build something slay, ily, bye ๐Ÿ’…๐ŸŽ€๐Ÿฆ‹
