phy_remove_link_mode(9)

💅 phy_remove_link_mode(9) — a Kernel API Manual moment

okay so bestie, welcome to phy_remove_link_mode, straight out of the Kernel API Manual. This is the little helper that goes "girl, you're not doing that link mode" and removes it. Periodt. 🎀

---

✨ NAME ✨

phy_remove_link_mode — Remove a supported link mode 🦋

---

🌸 SYNOPSIS 🌸

void phy_remove_link_mode (struct phy_device *phydev , u32 link_mode );

---

💖 ARGUMENTS 💖

• phydev — the phy_device structure you're removing the link mode from. Like, this is the PHY we're editing, bestie 🫶
• link_mode — the link mode that's getting yeeted. Removed. Gone. 💅

---

⭐ DESCRIPTION ⭐

okay so here's the tea ☕ — some MACs simply do not support all the link modes that the PHY does. Not their fault, they're just built different 😭. Example: a 1G MAC often does not support 1000Half. So the kernel adds this helper to remove a link mode. That's literally it. Iconic, lowkey ✨.

ngl bestie, that's a lot of friends. but like, main character energy requires a big group chat, iykyk 💀💜
