ice_write_intrl(9)

💅 ice_write_intrl(9) — like, the actual kernel API manual bestie 🫶

okay so picture this: we're deep in the ice driver, that's the Intel ethernet situation, and this lil function is your girl for writing a throttle rate limit into an interrupt specific register. that's the whole vibe. manual name is ice_write_intrl(9), in case you were wondering, and yes she's iconic for it ✨

---

🌸 NAME 🌸

ice_write_intrl — literally just writes the throttle rate limit to the interrupt specific register. that's it, that's the function, no cap 💖

---

🎀 SYNOPSIS 🎀

void ice_write_intrl (struct ice_q_vector *q_vector , u8 intrl );

look at her. returns nothing (void), takes two things. she's lowkey elegant 😭

---

🦋 ARGUMENTS 🦋

• q_vector — pointer to the interrupt specific structure. yes, that structure. the interrupt-specific one. she's holding the whole context for you, so be nice to her 🥺
• intrl — the throttle rate limit, in microseconds, that you want to write. it's a u8 btw, so it's smol. treat her accordingly 🌸
