okay so picture this: you're deep in the kernel API manual for ice_add_rss_cfg_wrap(9) and honestly? it's giving main character energy. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

ice_add_rss_cfg_wrap — literally just a wrapper for adding an RSS configuration 🎀

---

🌸 SYNOPSIS 🌸

int ice_add_rss_cfg_wrap (struct ice_vf *vf , struct ice_rss_hash_cfg
*cfg );

like, that's the whole signature. no notes. 💅

---

🦋 ARGUMENTS 🦋

• vf — pointer to the VF info 👑
• cfg — pointer to the RSS hash configuration ✨

---

🌈 DESCRIPTION 🌈

so what it actually does: it adds a flow profile based on an RSS configuration. that's the vibe.

but here's the part you cannot skip — it uses a rollback mechanism to handle rule conflicts, and those conflicts happen because of the TCAM write sequence going from top to down. so yeah, it's out here doing damage control so your rules don't get messy 🫶

---

⭐ RETURN ⭐

returns 0 on success; negative error code on failure. no cap. 😭
