ice_create_pkt_fwd_rule(9)

💖 NAME 💖

ice_create_pkt_fwd_rule — bestie, this is the Kernel API Manual, section 9 (ice_create_pkt_fwd_rule(9)), and the description line after the dash is literally empty in the source. Not me staring at a blank NAME field 😭. So: the function is ice_create_pkt_fwd_rule, and that's the whole vibe here.

---

✨ SYNOPSIS ✨

int ice_create_pkt_fwd_rule (struct ice_hw *hw , struct
       ice_fltr_list_entry *f_entry );

That's int in, int out, two args, no drama. 🫶

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure, aka the main character of this whole story 👑
• f_entry — entry containing packet forwarding information (yes, it's giving "the actual data you care about" 💅)

---

🌸 DESCRIPTION 🌸

okay so here's what it does, fr fr: it creates a switch rule using the filter information you hand it, and then it adds an entry to the corresponding filter management list — all so that this switch rule and its VSI mapping get tracked. That's it, that's the whole thing. Obsessed with a function that knows its lane ✨

that's the page, bestie 💜 it came from ./drivers/net/ethernet/intel/ice and it's dated October 2026 — don't ask me how a date in the future got into a manual page, that's just the source's business 🙈 slay, periodt ✨🎀
