phylink_replay_link_end(9)

💅 phylink_replay_link_end(9) — the i-lost-my-state glow-up, part two 🎀

okay so this is a page from the Kernel API Manual, bestie, and it's about phylink_replay_link_end — the little helper that ✨closes out✨ the link-callback replay for a driver that lost its state. yes we're doing lore today. sit down, hydrate, let's go 🧚

---

✨ NAME ✨

phylink_replay_link_end — literally "end replay of link callbacks for driver which lost state." that's it, that's the whole vibe. your driver blacked out 💀 and this is the part where it comes back online and we re-run the callbacks. periodt.

---

🦋 SYNOPSIS 🦋

void phylink_replay_link_end (struct phylink *pl );

it returns void, meaning: nothing comes back to you, it just does the thing. main character energy honestly 👑

---

🎀 ARGUMENTS 🎀

• pl — a pointer to a struct phylink returned from phylink_create. like, the actual object you got handed earlier. don't be out here inventing your own, i'm begging 🙈

---

🔥 DESCRIPTION 🔥

okay so picture this: you're a MAC driver. you might perform a destructive reset at runtime 😭 (yeah. destructive. like, wipes the slate). and after that the link callbacks are just… gone? stale? not it.

so this helper handles that. it calls:

• your own driver's mac_config and mac_link_up methods 💖
• and also the pcs_config and pcs_link_up method of the split PCS (if any — key words, iykyk)

the way it's basically phylink_start's cousin but with one big difference: this one does not alter the state of the phylib PHY. nope. not touching that. hands off 🫶

⚠️ the rule, bestie, do not skip it: you must call this method only within the same rtnl_lock critical section as a previous phylink_replay_link_start. same lock section. that's the whole assignment. it's giving matched set 💅
