i40e_add_stat_strings(9)

🌸 i40e_add_stat_strings — the Kernel API Manual page (section 9, bestie) 🌸

okay so real talk, this is i40e_add_stat_strings(9) straight out of the Kernel API Manual, and it's lowkey one of those tiny helper functions that just does its thing without any drama. ✨

---

💖 NAME 💖

i40e_add_stat_strings — copy stat strings into an ethtool buffer. that's it, that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

i40e_add_stat_strings (p , stats , ... );

literally the whole signature, no notes. 👑

---

🦋 ARGUMENTS 🦋

• p — the buffer that ethtool handed you. it's the destination, the main character of this story. 🫶
• stats — the stat definitions array. the source of truth, the blueprint, iykyk.
• ... — variable arguments. yes the literal three dots, they're doing work here. 💅

---

💜 DESCRIPTION 💜

so what this does is format and copy the strings described by the const static stats value into the buffer that p is pointing at. pretty, useful, iconic. ✨

⚠️ okay but listen — the parameter stats gets evaluated twice. TWICE. so if any of your parameters have side effects, avoid them, fr fr. side effects in a double-evaluated macro situation is giving chaos energy and nobody wants that. 😭

also, stats must be an array such that ARRAY_SIZE can be called on it. non-negotiable, bestie. no pointer tricks, no games. it has to be a real array. 🧚
