rte_eth_dev_tx_buffer(3)

πŸ“¦ version 26.03, in nixos 26.05, nixpkgs unstable

🌸 rte_eth_dev_tx_buffer 🌸

ok so bestie, welcome to rte_eth_dev_tx_buffer β€” that's the page name, and it's a section 3 (Library Functions Manual) situation, iykyk πŸ’…. This is a lil' struct that lives in the DPDK headers and it's literally the holding pen for packets waiting to go out the door. Let me walk you through it 🫢


✨ SYNOPSIS ✨

#include <rte_ethdev.h>

πŸŽ€ Data Fields

ok so here's the whole squad of fields, no cap:

  • uint16_t size
  • uint16_t length
  • struct rte_mbuf * pkts []

πŸ’– Detailed Description πŸ’–

So this struct is the one used to buffer packets for future Tx β€” like, future transmit, bestie, not a medical procedure 😭. It's the staging area before your packets hit the wire.

The APIs that use it are:

  • rte_eth_tx_buffer
  • rte_eth_tx_buffer_flush

Those two are the ones doing the actual work with this struct β€” this page is just the struct itself, main character energy but technically a supporting role πŸ‘‘

πŸ¦‹ Field Documentation πŸ¦‹

uint16_t size

Size of buffer for buffered Tx. So like, how much room the buffer has for this whole buffered-transmit situation ✨.

Definition at line 3919 of file rte_ethdev.h.

uint16_t length

Number of packets in the array β€” literally just a headcount of how many packets are chillin' in there rn πŸ“.

Definition at line 3920 of file rte_ethdev.h.

struct rte_mbuf* pkts[]

Pending packets to be sent on explicit flush or when full. So these babies get shipped out when you explicitly flush, or when the thing fills up all the way β€” whichever comes first πŸ’€.

aaaand that's the whole page, bestie! 🌈 This was DPDK, Version 26.03.0, and the page is rte_eth_dev_tx_buffer(3) β€” catch you on the next one, mwah πŸ’œπŸŽ€
