ice_fdir_update_cntrs(9)

💖 ice_fdir_update_cntrs(9) 💖

okay bestie, so this is a page from the Kernel API Manual — section 9, kernel API — and it's all about one tiny little function called ice_fdir_update_cntrs. that's the whole name section, we're done, slay ✨

---

✨ NAME ✨

ice_fdir_update_cntrs — increment / decrement filter counter 🎀

like. that's the whole personality. it counts filters. up or down. iconic behaviour honestly.

---

🌸 SYNOPSIS 🌸

void ice_fdir_update_cntrs (struct ice_hw *hw , enum ice_fltr_ptype flow
, bool add );

note the void — this one returns literally nothing, it just does its little counter thing and vibes. no return value, no drama, no exit status. periodt 💅

---

🦋 ARGUMENTS 🦋

three args, all of them important, let's go through them one by one:

• hw — pointer to hardware structure. yeah, it's the hardware struct. the main character. give it what it needs 🫶
• flow — filter flow type, as an enum ice_fltr_ptype. this is which flavour of flow we're talking about.
• add — a bool, and here's the tea: true implies filters added. that's it, that's the flag. if it's true we're going up, bestie 📈

ngl the argument descriptions are short and that's fine, don't come for me, that's literally all the page says 😭

buckle up, this list is LONG and we are NOT skipping a single one, the way this manpage cross-references itself is giving main character energy 👑
