ice_tc_set_ipv4(9)

💅 ice_tc_set_ipv4 — kernel API manual, bestie edition 🧚

okay so this is a page from the Kernel API Manual (yes, the real one, section 9, we're fancy now 👑) and it's all about one little function that yoinks IPv4 addresses out of a TC flower filter. let's get into it ✨

---

🌸 NAME 🌸

ice_tc_set_ipv4 — parses IPv4 addresses out of a TC flower filter. that's it, that's the whole job, and it does it slayfully 💖

---

✨ SYNOPSIS ✨

int ice_tc_set_ipv4 (struct flow_match_ipv4_addrs *match , struct
ice_tc_flower_fltr *fltr , struct ice_tc_flower_lyr_2_4_hdrs *headers ,
bool is_encap );

it returns an int, mwah 😘 — copy it exactly if you're typing it out, no cap, don't let autocorrect touch it.

---

🎀 ARGUMENTS 🎀

• match — pointer to the flow match structure. this is where the matched stuff lives 🫶
• fltr — pointer to the filter structure. the main character of the whole operation ngl 💅
• headers — inner or outer header fields. you pick which layer you're looking at, iconic behaviour honestly 🔥
• is_encap — set this to true for the tunnel IPv4 address. literally just that 🦋

bestie note: every single one of these is written with the (9) suffix because they're kernel API pages, so don't come for me about the parentheses, that's just how the section works 💀
