ice_set_rss_cfg_symm(9)

💖 ice_set_rss_cfg_symm — the glow-up your RSS config didn't know it needed 💖

okay so first of all, bestie, the original manpage has a lil typo in the NAME section — it says "symmtery" and honestly? iconic. we stan a slightly feral spelling moment. but fr fr, this function is the one that sets the symmetry for all VSI's RSS configurations, and it's giving main character energy.

this page lives in the Kernel API Manual and it's all about making your Receive Side Scaling get its symmetry act together. no cap.

✨ SYNOPSIS ✨

like, here's the vibe check on how you actually call this thing:

int ice_set_rss_cfg_symm(struct ice_hw *hw, struct ice_vsi *vsi, bool symm);

that's the whole signature, copy-pasted exactly, periodt. 💅

---

🎀 ARGUMENTS 🎀

• hw — a pointer to the hardware structure. it's literally the hardware's contact info. you know, the struct ice_hw * that holds all the juicy device details.
• vsi — the VSI you wanna set (or unset) Symmetric RSS on. VSI = Virtual Station Interface, and this one is your target bestie. you're telling this specific VSI to either slay symmetric hashing or not.
• symm — a bool. set it to TRUE to set Symmetric RSS hashing. and if you pass FALSE, well… you're unsetting it. that's it, that's the whole vibe. no mid behavior. ✨

lowkey important: TRUE means symmetric RSS hashing is on. don't get it twisted. 🙈

that's the whole page, bestie. ice_set_rss_cfg_symm — it's giving symmetry, it's giving kernel API, it's giving slay. go forth and configure your RSS with confidence. 💜

🧚 cute lil sign-off: this page comes from ./drivers/net/ethernet/intel/ice and the date on the original is October 2026. so like, future vibes only. ✨🌸
