💖 iavf_set_ringparam(9) — the Kernel API Manual glow-up ✨

okay bestie, welcome to the Kernel API Manual entry for iavf_set_ringparam — it's giving "small function, big responsibilities" and we're gonna get into it 🎀

✨ NAME ✨

iavf_set_ringparam — literally just: Set ring parameters 💅 no cap, that's the whole job.

🌸 SYNOPSIS 🌸

int iavf_set_ringparam (struct net_device *netdev , struct
       ethtool_ringparam *ring , struct kernel_ethtool_ringparam *kernel_ring ,
       struct netlink_ext_ack *extack );

look at her. four arguments, returns an int, absolutely main character energy 👑

🦋 ARGUMENTS 🦋

  • netdev — the network interface device structure, aka the whole vibe of the NIC you're messing with 🫶
  • ring — the ethtool ringparam structure, where the actual ring settings live ✨
  • kernel_ring — the ethtool external ringparam structure, the kernel-side counterpart 🧚
  • extack — the netlink extended ACK report struct, there to carry back the tea if something goes wrong ☕😭

💜 DESCRIPTION 💜

So here's the deal, bestie: this one sets ring parameters. TX and RX rings are controlled separately, which is honestly so iconic of them — but plot twist 🫢 the number of rings is not specified, so literally all the rings get the same settings. every single one. same fit, same energy. periodt 💀✨

💀 reminder that the number of rings isn't a parameter here, so don't come for her asking for per-ring control — everybody's getting the same settings, iykyk.

and that's the page, bestie!! 🍓 this lil rewrite came straight out of ./drivers/net/ethernet/intel/iavf — Kernel API Manual, October 2026 edition — go drink some water and go read your ring params 💖✨🫶
