phylink_caps_to_linkmodes(9)

💅 phylink_caps_to_linkmodes(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for phylink_caps_to_linkmodes(9). this one's short and sweet and honestly kind of a little slay 💖

---

🌸 NAME 🌸

phylink_caps_to_linkmodes — literally converts capabilities into ethtool link modes, that's the whole vibe 🦋

---

🎀 SYNOPSIS 🎀

void phylink_caps_to_linkmodes (unsigned long *linkmodes , unsigned long caps );

---

✨ ARGUMENTS ✨

• linkmodes — the ethtool linkmode mask. and listen, it must be already initialised, no cap 🫶 like it's not optional, it's giving "you better have done this already".
• caps — the bitmask of MAC capabilities. this is the input glow-up material 💅

---

🔥 DESCRIPTION 🔥

so what does it do? it sets all possible pause, speed and duplex linkmodes inside linkmodes that are supported by caps. iconic behavior honestly 👑

and again, because it bears repeating: linkmodes must have been initialised previously. that's the rule, periodt 💀

⚠️ quick vibe check: the initialisation thing is not a suggestion, bestie — get that done first or it's not gonna go well 😭
