ice_add_rss_cfg_pre_ip(9)

💅 ice_add_rss_cfg_pre_ip — like, the pre-game for IP-layer RSS config ✨

okay so this one lives in the Kernel API Manual (section 9, kernel-space girlies rise 🫶), and it's basically the opening act before the main character shows up. let's get into it 💖

---

🌸 SYNOPSIS 🌸

int ice_add_rss_cfg_pre_ip (struct ice_vf *vf , struct
       ice_vf_hash_ip_ctx *ctx );

literally the whole signature, no cap. yes the line break is real, we don't make the rules 😭

---

🎀 ARGUMENTS 🎀

• vf — VF pointer 💫 (the virtual function bestie in question)
• ctx — IP L4 hash context 👑 — and before you ask, that covers ESP/UDP-ESP/AH/PFCP and UDP/TCP/SCTP. so many vibes in one struct fr fr

---

🦋 DESCRIPTION 🦋

okay so here's the tea: this function removes covered/recorded IP RSS configurations prior to adding a new one. 🧹✨

it's giving cleanup era. before anything new gets added, the old covered/recorded stuff gets cleared out. main character energy: out with the old, in with the new 💅

---

🔥 RETURN 🔥

• 0 — success, we ate 🍓✨
• negative error code — failure, and honestly 💀 (it's negative, so you know something went wrong)
