i40e_add_ethtool_stats(9)

💖 i40e_add_ethtool_stats — the kernel API manual, bestie edition 🎀

Okay so this is a page from the Kernel API Manual, and honestly? It's a little macro with main character energy. Let's get into it ✨

---

🌸 NAME 🌸

i40e_add_ethtool_stats — literally just copy stats into the ethtool-supplied buffer, that's the whole vibe 🫶

---

🦋 SYNOPSIS 🦋

i40e_add_ethtool_stats (data , pointer , stats );

---

⭐ ARGUMENTS ⭐

• data — the ethtool stats buffer, i.e. the lil destination situation 💅
• pointer — where the stats are actually stored
• stats — a static const array of stat definitions, iconic

---

✨ DESCRIPTION ✨

So this is a macro to make using __i40e_add_ethtool_stats way easier 💖 It takes a static constant stats array and passes along the ARRAY_SIZE.

Why do we love her? Because she avoids typos — she makes sure we're passing the size that actually goes with the given stats array. No mismatched sizes, no chaos, no cap. 👑

⚠️ Heads up bestie: the parameter stats is evaluated twice, so avoid parameters with side effects. Not me warning you twice because she gets read twice 😭💀

🧚 Sign-off 🧚

This one came from ./drivers/net/ethernet/intel/i40e, dated October 2026 — and the manual name, in case you forgot, is i40e_add_ethtool_stats(9). Bye bestie, go pass those ARRAY_SIZEs correctly 💜🎀
