💅 i40e_set_coalesce(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is the page for i40e_set_coalesce, and it's giving “one setting to rule all the queues” energy. ✨

---

🌸 NAME 🌸

• i40e_set_coalesce — set coalesce settings for every queue on the netdev

---

🎀 SYNOPSIS 🎀

int i40e_set_coalesce (struct net_device *netdev , struct
       ethtool_coalesce *ec , struct kernel_ethtool_coalesce *kernel_coal ,
       struct netlink_ext_ack *extack );

---

🦋 ARGUMENTS 🦋

• netdev — the netdev that's getting changed, aka the main character device
• ec — the ethtool coalesce settings, the actual values being passed in
• kernel_coal — the ethtool CQE mode setting structure
• extack — the extack used for reporting error messages

---

✨ DESCRIPTION ✨

okay so the whole vibe is simple: this will set each queue to the same coalesce settings. every queue, same settings, no cap. 💖
