fm10k_restore_udp_port_info(9)

💅 fm10k_restore_udp_port_info — from the Kernel API Manual (section 9, bestie) ✨

Okay so welcome to the glow-up era of the kernel docs. This page lives in the Kernel API Manual, section 9, and it's all about one lil function that has one job and does it slayfully.

🎀 NAME 🎀

fm10k_restore_udp_port_info —

(no cap, the original name line just trails off with a dash, so like… the name IS the description here. main character energy. iykyk 💅)

---

✨ SYNOPSIS ✨

void fm10k_restore_udp_port_info (struct fm10k_intfc *interface );

That's it. It returns void, it takes one pointer, and it has zero drama. periodt.

---

🫶 ARGUMENTS 🫶

• interface — the board private structure 💖 literally the fm10k interface struct you're handing over so it can do its thing.

---

🌸 DESCRIPTION 🌸

So here's the vibe check: after a reset happens, this function restores the value in the tunnel_cfg register(s). That's the whole assignment, and it ate. 🔥

Think of it like this — reset just wiped the tunnel_cfg register(s) back to factory settings (rude), and fm10k_restore_udp_port_info is the bestie who shows up after and puts your UDP tunnel port config back exactly how you had it. no cap, no notes. 🦋

It's void, so don't be waiting around for a return value — there isn't one, she simply does the thing and dips. 😭

💜 quick reminder bestie: this page is sourced from ./drivers/net/ethernet/intel/f... (the truncated-looking one, yeah that's literally how it's printed, don't @ me) and it's dated October 2026. Drink some water, go read fm10k_netdev.c, and stan a kernel function that only does one thing. 🍓🧚✨
