idpf_get_ringparam(9)

💅 idpf_get_ringparam — a Kernel API Manual moment (section 9, bestie)

okay so you found yourself in the Kernel API Manual, specifically the idpf_get_ringparam(9) page, and honestly? slay. it's giving "i'm reading kernel docs for fun" main character energy. let's get into it 🎀

---

✨ NAME ✨

idpf_get_ringparam — literally just Get ring parameters. that's the whole vibe. nothing more, nothing less 🦋

---

🌸 SYNOPSIS 🌸

void idpf_get_ringparam (struct net_device *netdev , struct
       ethtool_ringparam *ring , struct kernel_ethtool_ringparam *kring ,
       struct netlink_ext_ack *ext_ack );

so it returns void (no return value, she just does her thing and leaves 💅) and takes four arguments. write it exactly like that, no cap, don't be out here renaming stuff 🙈

---

🫶 ARGUMENTS 🫶

• netdev — the network interface device structure. this is THE device, the moment, the icon 👑
• ring — the ethtool_ringparam structure. the ring params live here, that's where the tea gets reported 🍓
• kring — unused. she's there, she's listed, she's not doing anything. we love a chill spectator 🌈
• ext_ack — also unused. same energy. just vibing in the parameter list ✨

---

💖 DESCRIPTION 💖

so what does it actually do? it returns current ring parameters. that's it, that's the function 🫶

here's the important bit though, bestie, don't miss this: TX and RX rings are reported separately, but the number of rings is not reported. so like, the individual TX and RX info shows up, but the count? not invited to the party 💀 no ring count for you. periodt.
