idpf_set_q_coalesce(9)

💅 idpf_set_q_coalesce — set ITR values for specific queue

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function page from the kernel docs and it's literally about tuning one specific queue's coalescing vibes. let's get into it 🫶

---

🌸 SYNOPSIS 🌸

int idpf_set_q_coalesce (const struct idpf_vport *vport , struct
       idpf_q_coalesce *q_coal , const struct ethtool_coalesce *ec , int q_num
       , bool is_rxq );

that's the whole signature, no cap — copy it exactly if you're typing it out 💖

---

🎀 ARGUMENTS 🎀

• vport — the vport that's associated with the queue you're updating. like, which vport owns this queue? that one. 💫
• q_coal — the per-queue coalesce settings. this is the per-queue lil settings holder, okurr ✨
• ec — the coalesce settings you actually want to program the device with. this is the payload, the main character of the operation 👑
• q_num — update the ITR/INTRL (coalesce) settings for this queue number/index. yes, this specific one, not a different one 🙈
• is_rxq — is the queue type rx? that's the whole question this bool is asking 💀

---

🦋 DESCRIPTION 🦋

so what does it do? it sets the ITR values for a specific queue, bestie — that's the whole vibe. per the docs:

Return 0 on success, and negative on failure

that's it, that's the contract. zero = slay, negative = something went sideways 😭

okay and finally, the lil sign-off moment 🎀 this page comes from ./drivers/net/ethernet/intel/idpf and it's dated October 2026 — so yeah, future-coded of it honestly ⭐ bye bestie, go set some coalesce values 💜
