ice_net_dim(9)

💖 ice_net_dim(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — yes this is ice_net_dim, the little glow-up function that tells the net DIM algorithm what's up. it lives in ./drivers/net/ethernet/intel/ice and honestly? she's serving utility. 🎀

---

🌸 NAME 🌸

ice_net_dim — update the net DIM algorithm 👑 lowkey the whole job description right there

---

🦋 SYNOPSIS 🦋

void ice_net_dim (struct ice_q_vector *q_vector );

like, that's it. one argument. tiny footprint, main character energy 💅

---

✨ ARGUMENTS ✨

• q_vector — the vector associated with the interrupt 🫶 that's the one (1) thing she needs from you

---

💜 DESCRIPTION 💜

so what she does is: create a DIM sample and notify net_dim, so that it can possibly decide a new ITR value based on incoming packets, bytes, and interrupts. 📊✨ like she's handing over the receipts and letting net_dim do the math.

and here's the part where you go "wait—" 🙈: this function is a no-op if the ring is not configured to dynamic ITR. literally does nothing. zero. zilch. she's not mad, she's just not being called to the group chat. 💀

<div>no cap, that's the whole behaviour. no extra tricks, no hidden vibes.</div>
