🌸 phylink_ethtool_nway_reset — restart negotiation, bestie 🌸

Ok so this is a page from the Kernel API Manual (the phylink_ethtool_nway_reset(9) one, yes the whole thing is named after the function, iconic behavior honestly) and we're gonna get you comfy with it. Buckle up 💖

✨ NAME ✨

phylink_ethtool_nway_reset — restart negotiation 💅

---

🦋 SYNOPSIS 🦋

int phylink_ethtool_nway_reset (struct phylink *pl );

---

🎀 ARGUMENTS 🎀

• pl — a pointer to a struct phylink returned from phylink_create 🫶 like, that's it, that's the whole argument, she's low maintenance.

---

💜 DESCRIPTION 💜

So what does she do? She restarts negotiation for the phylink instance you pointed at with pl. Periodt.

Which means: any attached phy is gonna restart negotiation with the link partner 🔥 and — plot twist — if the MAC is in a BaseX mode, the MAC will also be requested to restart negotiation. Not me having two whole things restarting at once 😭 the multitasking is giving main character energy.

Returns zero on success, or a negative error code 👑 so like, check the return value fr fr, that's your vibe check on whether it worked.
