rte_eth_fc_conf(3)

💖 rte_eth_fc_conf — NAME 💖

okay bestie, say hi to rte_eth_fc_conf — it's a struct, it lives in the DPDK library functions manual, and it's literally the lil control panel you use to set up Ethernet flow control parameters. yes. that one. 💅

---

✨ SYNOPSIS ✨

First, the incantation:

#include <rte_ethdev.h>

🎀 Data Fields 🎀

here's the whole squad, in order, no cap:

uint32_t high_water
uint32_t low_water
uint16_t pause_time
uint16_t send_xon
enum rte_eth_fc_mode mode
uint8_t mac_ctrl_frame_fwd
uint8_t autoneg

---

🦋 Detailed Description 🦋

so like, this is a structure used to configure Ethernet flow control parameters. the way that it works is: these parameters will be configured into the register of the NIC. that's it, that's the job. 👑

and bestie, please — please — refer to the corresponding data sheet for the proper value. DPDK is not gonna hold your hand on the numbers, and I'm not about to invent any. 🙈
