🎀 __i40e_get_coalesce(9) 💖 Kernel API Manual 🎀

Okay bestie, welcome to the Kernel API Manual corner of the group chat ✨ This one is all about __i40e_get_coalesce, and it is giving “small function, very specific job, absolutely knows what it’s doing” energy 💅

---

✨ NAME ✨

__i40e_get_coalesce — get per-queue coalesce settings 🫶

---

🌸 SYNOPSIS 🌸

int __i40e_get_coalesce (struct net_device *netdev , struct
       ethtool_coalesce *ec , int queue );

---

🫶 ARGUMENTS 🫶

• netdev — the netdev to check 👀
• ec — the ethtool coalesce data structure 🎀
• queue — which queue to pick, like choosing your main character queue 💅

---

💅 DESCRIPTION 💅

So this function gets the per-queue settings for coalescence ✨ Specifically, the Rx and Tx usecs are per queue. If queue is <0, then we default to queue 0 as the representative value. Lowkey iconic behavior, no cap 💖
