💅 ixgbe_validate_link_ready(9) 💅

okay bestie, buckle up — this is a page from the Kernel API Manual (section 9, the kernel-functions girlies), and it's all about ixgbe_validate_link_ready, a function whose entire personality is "is the phy link up yet? is it? is it? 👀"

---

✨ NAME ✨

ixgbe_validate_link_ready — the function that goes looking for the phy link 🔍🦋

---

🌸 SYNOPSIS 🌸

int ixgbe_validate_link_ready (struct ixgbe_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. that's the hardware struct, the main character of this whole operation 💅

---

🔥 DESCRIPTION 🔥

so basically, this function is out here indicating success when the phy link is available. iconic behavior, no notes. ✨

but here's the tea: if the phy is not ready within 5 seconds of the MAC indicating link, the function returns an error. 😭 five whole seconds, bestie — the clock is ticking fr fr.

ngl, that 5 seconds window is the whole vibe check of this function. miss it and you're getting an error back, periodt.
