ice_hash_cfg_reset(9)

💅 ice_hash_cfg_reset — the kernel API page, but make it make sense

okay so bestie, this is a page from the Kernel API Manual, and the star of the show is ice_hash_cfg_reset. It's giving "tiny function, big responsibilities" energy, and honestly? We're obsessed. Let's get into it 🫶

---

✨ NAME ✨

ice_hash_cfg_reset — reset an RSS hash context. That's it, that's the whole vibe check. 🎀

---

🌸 SYNOPSIS 🌸

void ice_hash_cfg_reset (struct ice_rss_hash_cfg *cfg );

no return value, no drama, just vibes and a pointer. periodt. 💅

---

🦋 ARGUMENTS 🦋

• cfg — the RSS hash configuration you're resetting. This is the lil struct we're about to wipe clean, bestie. ✨

---

🔥 DESCRIPTION 🔥

So here's the tea: ice_hash_cfg_reset resets the fields of cfg that store the active rule information. That's the whole job. It's not doing the most, it's not overachieving — it's just quietly clearing out the active-rule data in that struct so you can start fresh. lowkey iconic behaviour, ngl. 👑

fr fr though — the important detail is which fields get reset: only the ones holding the active rule info. Don't go assuming it nukes the whole struct, because the page does not say that and neither will I. 💀

that's the whole page bestie, go reset some hash configs responsibly 💖

shoutout to the source ./drivers/net/ethernet/intel/i... (yes, the manpage footer truncates it just like that — I'm not gonna lie to you and pretend it says more) and the date October 2026, which is when this little gem got stamped. mwah. 😘🌸
