ice_set_link_ksettings(9)

💅 ice_set_link_ksettings(9) — the Kernel API Manual, bestie edition 💅

Okay so picture this: you're deep in the Kernel API Manual, section 9, and you've stumbled onto ice_set_link_ksettings. Bestie. This is the one that sets your Speed and Duplex. Let's get into it, no cap. 🫶

✨ NAME ✨

ice_set_link_ksettings — literally just Set Speed and Duplex. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int ice_set_link_ksettings (struct net_device *netdev , const struct
       ethtool_link_ksettings *ks );

She returns an int, she takes two things, and she's on her main character grind. ✨

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure. The whole device, the icon, the moment. 👑
• ks — the ethtool ksettings. Your settings bestie, arriving with opinions. 🎀

---

💖 DESCRIPTION 💖

So what does she actually do? She sets speed/duplex per the media_types that are advertised/forced. That's it, that's the whole assignment, and she ate. 🔥

Not me being obsessed with how short this description is — honestly? Iconic. Short and correct is a vibe. 💅

💀 Real talk though: this page is from the ./drivers/net/ethernet/intel/ice directory, dated October 2026, and it's ice_set_link_ksettings(9) all the way down. Go set some speed and duplex, bestie. Slay. 👑✨
