i40e_get_coalesce(9)

💖 i40e_get_coalesce(9) 💖

okay so this is a page from the Kernel API Manual — yes, the kernel has its own manual, she's iconic like that 💅

---

✨ NAME ✨

i40e_get_coalesce — literally just goes and grabs a netdev's coalesce settings 🫶

---

🌸 SYNOPSIS 🌸

int i40e_get_coalesce (struct net_device *netdev , struct
       ethtool_coalesce *ec , struct kernel_ethtool_coalesce *kernel_coal ,
       struct netlink_ext_ack *extack );

like, she takes four things and returns an int, no cap ✨

---

🎀 ARGUMENTS 🎀

• netdev — the netdev bestie you wanna check 👀
• ec — the ethtool coalesce data structure, that's her whole personality
• kernel_coal — the ethtool CQE mode setting structure 🦋
• extack — the extack, there so error messages can actually be reported back to you 💌

---

💜 DESCRIPTION 💜

So basically it gets the coalesce settings for a particular netdev. That's the whole vibe. 🌈

⚠️ but lowkey important: if the user has modified per-queue settings, this only guarantees to represent queue 0. fr fr, queue 0 only. 😭

if you want more details, go see __i40e_get_coalesce — she's the main character here 🔥
