igc_phy_has_link(9)

✨ NAME ✨

okay so bestie, welcome to the igc_phy_has_link(9) page from the Kernel API Manual 💖 — this one is lowkey giving “poll the PHY for link” energy and we’re here for it.

igc_phy_has_link — Polls PHY for link 👀

🌸 SYNOPSIS 🌸

s32 igc_phy_has_link (struct igc_hw *hw , u32 iterations , u32
       usec_interval , bool *success );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🧚
• iterations — number of times to poll for link 🔁
• usec_interval — delay between polling attempts ⏳
• success — pointer to whether polling was successful or not ✅

🦋 DESCRIPTION 🦋

So the vibe is: it polls the PHY status register for link, 'iterations' number of times 💅. That’s the whole main-character move — PHY status register, link, polled 'iterations' times. Periodt.
