🎀 rte_eth_txconf — Library Functions Manual 🎀

okay bestie so welcome to rte_eth_txconf(3), the DPDK struct that handles your Ethernet port's Tx ring config and honestly? it's giving "quietly essential" 💅 she doesn't post much but she runs the whole outfit.

✨ NAME ✨

rte_eth_txconf — the struct you fill in to tell an Ethernet port how to configure one of its Tx rings 👑

🌸 SYNOPSIS 🌸

#include <rte_ethdev.h>

🌈 Data Fields 🌈

struct rte_eth_thresh tx_thresh
uint16_t tx_rs_thresh
uint16_t tx_free_thresh
uint8_t tx_deferred_start
uint64_t offloads
uint64_t reserved_64s [2]
void * reserved_ptrs [2]

💖 DETAILED DESCRIPTION 💖

A structure used to configure a Tx ring of an Ethernet port. no cap, that's literally her whole job.

Definition at line 1214 of file rte_ethdev.h.

🦋 FIELD DOCUMENTATION 🦋

  • struct rte_eth_thresh tx_thresh — the Tx ring threshold registers. where the ring's thresholds live, periodt. Definition at line 1215 of file rte_ethdev.h.
  • uint16_t tx_rs_thresh — drives the setting of the RS bit on TXDs. she's the one deciding when that RS bit gets flipped 🔥 Definition at line 1216 of file rte_ethdev.h.
  • uint16_t tx_free_thresh — start freeing Tx buffers if there are less free descriptors than this value. so like, the "bestie we're running low" alarm for descriptors 🫶 Definition at line 1217 of file rte_ethdev.h.
  • uint8_t tx_deferred_start — do not start the queue with rte_eth_dev_start(). yes that's the whole point of her, she's the "not yet bestie" flag 🙈 Definition at line 1220 of file rte_ethdev.h.
  • uint64_t offloads — per-queue Tx offloads to be set using RTE_ETH_TX_OFFLOAD_* flags. Only offloads set on tx_queue_offload_capa or tx_offload_capa fields on rte_eth_dev_info structure are allowed to be set. ok so read this part twice because it's the rule: if it's not in those capa fields, you cannot set it. she will not be flexible on this 😭 Definition at line 1226 of file rte_ethdev.h.
  • uint64_t reserved_64s[2] — reserved for future fields. packing peanuts for the future 🎀 Definition at line 1228 of file rte_ethdev.h.
  • void* reserved_ptrs[2] — reserved for future fields. more packing peanuts, pointer flavoured ⭐ Definition at line 1229 of file rte_ethdev.h.
