phylink_get_link_timer_ns 💅

okay so bestie, we're in the Kernel API Manual today (yes, that's the manual name, don't @ me) — and this little function is lowkey iconic. it's phylink_get_link_timer_ns, and it's here to hand you the PCS link timer value. let's get into it ✨

---

🎀 NAME 🎀

phylink_get_link_timer_ns — returns the PCS link timer value. that's it, that's the whole vibe. no cap. 🫶

---

⭐ SYNOPSIS ⭐

int phylink_get_link_timer_ns(phy_interface_t interface);

like, it takes one thing and gives you back an int. simple. elegant. main character energy fr fr. 💖

---

🦋 ARGUMENTS 🦋

• interface — your link typedef phy_interface_t mode. that's the mode, bestie, the whole mood of the link. it's giving "tell me what kind of interface we're on and i'll do the math". 🧚

---

🌸 DESCRIPTION 🌸

so what does it do? okay legend, here's the tea ☕:

it returns the PCS link timer setting in nanoseconds for the PHY interface mode. nanoseconds!! we love a precise queen. ⏱️✨

but — and this is the important part — if it's not appropriate for that mode? it hits you with -EINVAL. not a vibe, but them's the rules. so check your mode before you come crying to me 😭

literally that's the whole contract: nanoseconds for the interface mode, or -EINVAL if it's not appropriate. no guessing, no extra lore. 💀
