ice_is_hash_cfg_valid(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ice_is_hash_cfg_valid — the vibe check for your RSS hash config ✨

Okay bestie, welcome to the Kernel API Manual — specifically the ice_is_hash_cfg_valid(9) page, aka the tiny little gatekeeper that decides whether your RSS hash context is actually valid or just... not. 🫶

🌸 NAME 🌸

ice_is_hash_cfg_valid — check whether an RSS hash context is valid 💅

Like literally, that's its whole job. It looks at your config and goes "valid" or "not valid." No drama, no notes.

✨ SYNOPSIS ✨

bool ice_is_hash_cfg_valid (struct ice_rss_hash_cfg *cfg );

Short, sweet, takes one pointer. Obsessed. 🎀

🦋 ARGUMENTS 🦋

  • cfg — the RSS hash configuration you want to test, bestie. It's a struct ice_rss_hash_cfg *, so yes, you're passing a pointer. Respect the pointer. 🙈

⭐ RETURN ⭐

It returns true when both cfg->hash_flds and cfg->addl_hdrs are non-zero. If either one is zero? It returns false. That's it. That's the whole test. No cap. 🔥

Fr fr, note the "both" — it's an AND situation, not an OR situation. One of them being non-zero is not enough to slay here. 💀

🌈 SEE ALSO 🌈

First up, the kernel file where all this lives, in all its glory:

./drivers/net/ethernet/intel/ice/virt/rss.c

And then the whole friend group, because this function does not exist in isolation, bestie:

Like, that's a whole squad. Go read about them too. 👑

That's the page, bestie — go forth and validate those hash configs. 🧚💜

Sign-off era: this one's from ./drivers/net/ethernet/intel/i..., dated October 2026, and it's the ice_is_hash_cfg_valid(9) page. Mwah. 💋🍓
