🌸 NAME 🌸

ice_add_rss_cfg_pre — Prepare RSS configuration context for a VF

okay bestie, this is ice_add_rss_cfg_pre(9) from the Kernel API Manual, and it's giving “prep the RSS config context for a VF” energy. very niche, very iconic 💅

---

✨ SYNOPSIS ✨

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

---

🎀 ARGUMENTS 🎀

• vf — pointer to the VF structure, aka the profile we're setting up.
• cfg — pointer to the RSS hash configuration, aka the vibe settings.

---

🦋 DESCRIPTION 🦋

okay so picture this: you've got a VF and a cfg full of extra protocol headers, and this function preps the RSS hash context for that VF based on those headers. It includes pre-configuration for IP and GTPU-based flows, no cap.

If the configuration matches a known IP context, the function sets up the appropriate IP hash context. If the configuration includes GTPU headers, it prepares the GTPU-specific context accordingly. that's the whole lore ✨

---

💖 RETURN 💖

0 on success, or a negative error code on failure. slay when it's zero, sad trombone when it's negative 😭
