idpf_add_one_ethtool_stat(9)

💖 idpf_add_one_ethtool_stat(9) 💖

okay so this is a page from the Kernel API Manual bestie, and it's about one tiny little helper that copies a stat into the buffer you hand it. short king behavior, honestly. 🎀

---

✨ SYNOPSIS ✨

void idpf_add_one_ethtool_stat (u64 *data , const void *pstat , const struct idpf_stats *stat );

---

🌸 ARGUMENTS 🌸

• data — the spot where you want the stat value to land. it's where the copying to happens, bestie 💅
• pstat — the old stat pointer, aka where we're copying from. the source of truth, the original, the blueprint 🦋
• stat — the stat definition itself. the little struct that tells us what we're even dealing with ✨

---

💜 DESCRIPTION 💜

so here's the vibe: it copies the stat data that's defined by the pointer + stat structure pair into the memory you passed in as data. that's it. that's the whole job. 🫶

but — and this is the important part — if the pointer is null, then data gets zero'd instead. no pointer, no data, so it just fills it with zeros. lowkey considerate of it, ngl 💀

no surprises here, it's giving "small function that does exactly one thing and does it well." main character energy, honestly 👑

and that's the whole page, bestie, you're officially an idpf stat expert 🧚💖 this came out of ./drivers/net/ethernet/intel/idpf and it's dated October 2026 — go forth and copy those stats, ily, bye! 🌸💅
