idpf_set_coalesce(9)

💖 idpf_set_coalesce — bestie, let's set those ITR values 💖

Okay so real talk, this page is from the Kernel API Manual (section 9, kernel internals, very 🧚 main-character energy) and it's all about idpf_set_coalesce — which does exactly what it says on the tin: it sets ITR values as requested by the user. Slay. ✨

---

🦋 SYNOPSIS 🦋

int idpf_set_coalesce (struct net_device *netdev , struct
       ethtool_coalesce *ec , struct kernel_ethtool_coalesce *kec , struct
       netlink_ext_ack *extack );

Like, four args, one int return, no cap. 💅

---

🌸 ARGUMENTS 🌸

• netdev — pointer to the netdev associated with this query. It's giving "which interface are we even talking about" energy 🎀
• ec — the coalesce settings to program the device with. This is the actual payload, the moment, the reason we're all here 💖
• kec — unused. Literally just sitting there. Not me ignoring it 🙈
• extack — unused too. Also just vibing. Nothing to see here 🫶

---

⭐ DESCRIPTION ⭐

Return 0 on success, and negative on failure. That's it. That's the whole description. Lowkey iconic for how short it is 💀✨

Heads up bestie: the kec and extack params are genuinely marked unused here, so don't go passing them expecting magic. They're decorative. 🎀

And that's the page!! This little love letter lives in ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's brought to you by section 9 of the manual — the kernel API manual, where all the fun stuff hangs out. Bye bestie, go set some ITR values 💜🦋🌸
